I'm running snmptt as a SNMP trap handler for snmptrapd, with the aim being to write to a trap file that can be read and processed by Zabbix. I have set up snmptt to run as the zabbix user by changing the init script. # grep daemon /etc/init.d/snmptt # description: SNMP Trap Translator daemon # Short-Description: SNMP Trap Translator daemon OPTIONS="--daemon" daemon --user=zabbix /usr/sbin/snmptt $OPTIONS snmpttt is running as expected as the zabbix user, the same user which is running the Zabbix server. # ps -ef | grep snmp root 3796 1 0 Jun19 ? 00:13:04 /usr/sbin/snmpd -LS0-6d -Lf /dev/null -p /var/run/snmpd.pid zabbix 4444 1 0 15:00 ? 00:00:00 /usr/bin/perl /usr/sbin/snmptt --daemon zabbix 4445 4444 0 15:00 ? 00:00:00 /usr/bin/perl /usr/sbin/snmptt --daemon root 9300 29899 0 15:25 pts/2 00:00:00 grep snmp zabbix 16576 16511 0 Aug16 ? 00:00:11 /path/to/sbin/zabbix_server: snmp trapper [processed data in 0.000007 sec, idle 1 sec] root 16600 1 0 Aug16 ? 00:00:07 /usr/sbin/snmptrapd -A -Lf /var/log/snmptrapd.log -D -p /var/run/snmptrapd.pid The log file to send traps caught is /var/tmp/zabbixtest/zabbix_traps.tmp # egrep "^(log_file|pid)" /etc/snmp/snmptt.ini pid_file = /var/run/snmptt/snmptt.pid log_file=/var/tmp/zabbixtest/zabbix_traps.tmp However, the trap log file is being written to, and owned by the root user, not as the zabbix user as expected. Moreover, the permissions on the file are 0640, meaning that the zabbix user running the server is not able to read the file. # service snmptt stop Stopping snmptt: [ OK ] # rm /var/tmp/zabbixtest/zabbix_traps.tmp rm: remove regular file `/var/tmp/zabbixtest/zabbix_traps.tmp'? y # ls -lia /var/tmp/zabbixtest/zabbix_traps.tmp ls: cannot access /var/tmp/zabbixtest/zabbix_traps.tmp: No such file or directory # ls -lia /var/tmp/zabbixtest/ total 24 263224 drwxrwxr-x 2 root zabbix 4096 Aug 17 15:32 . 262145 drwxrwxrwt 7 root root 4096 Aug 17 14:53 .. # service snmptt start Starting snmptt: PID file: /var/run/snmptt/snmptt.pid [ OK ] # ps -ef | grep snmptt zabbix 9944 1 0 15:32 ? 00:00:00 /usr/bin/perl /usr/sbin/snmptt --daemon zabbix 9945 9944 0 15:32 ? 00:00:00 /usr/bin/perl /usr/sbin/snmptt --daemon root 9981 29899 0 15:32 pts/2 00:00:00 grep snmptt # ps -ef | grep snmp root 3796 1 0 Jun19 ? 00:13:04 /usr/sbin/snmpd -LS0-6d -Lf /dev/null -p /var/run/snmpd.pid zabbix 9944 1 0 15:32 ? 00:00:00 /usr/bin/perl /usr/sbin/snmptt --daemon zabbix 9945 9944 0 15:32 ? 00:00:00 /usr/bin/perl /usr/sbin/snmptt --daemon root 9986 29899 0 15:32 pts/2 00:00:00 grep snmp zabbix 16576 16511 0 Aug16 ? 00:00:11 /path/to/sbin/zabbix_server: snmp trapper [processed data in 0.000079 sec, idle 1 sec] root 16600 1 0 Aug16 ? 00:00:07 /usr/sbin/snmptrapd -A -Lf /var/log/snmptrapd.log -D -p /var/run/snmptrapd.pid # ls -lia /var/tmp/zabbixtest/zabbix_traps.tmp 262265 -rw-r----- 1 root root 122 Aug 17 15:32 /var/tmp/zabbixtest/zabbix_traps.tmp Note the file permissions and ownership of /var/tmp/zabbixtest/zabbix_traps.tmp. Accordingly, the zabbix user is unable to read the file and is hence unable to process it. I can fix by manually modifying the mode of the trap file /var/tmp/zabbixtest/zabbix_traps.tmp to 0644, for example, but I am hoping there is a better way, e.g. via a configuration file, since the file location will most likely change. (There are some blog sites recommending to change the mode to 0777, obviously that is not the correct solution). I guess it is due to the snmptrapd configuration, running as root, but not sure the best way to fix this. **My questions:** Why is the trap log file being written to as the root user with 0640 permissions, instead of as zabbix user running snmptt? How can/should I configure snmptt and/or snmptrapd to have the trap file be owned and readable by the zabbix user instead of root user. **Other relevant info:** snmptrapd config file: # grep -v '^#' /etc/snmp/snmptrapd.conf disableAuthorization yes traphandle default /usr/sbin/snmptthandler Running RHEL 6.6

What should I do, I have set up everything for what I thought would be a wonderful well running zabbix server and now it is not running on the final step. I cannot figure out what went wrong. How can I fix this? this is my first time, please help thanks :) ?php // Zabbix GUI configuration file. $DB['TYPE'] = 'MYSQL'; $DB['SERVER'] = 'localhost'; $DB['PORT'] = '0'; $DB['DATABASE'] = 'zabbix'; $DB['USER'] = 'zabbix'; $DB['PASSWORD'] = 'zabbix_db_pass'; // Schema name.

Can anyone give me some help on finding a guide compatible with CentOS Linux release 7.9,2009 (core)

I know there are several topics about fping and zabbix, but I've read through them all and I am still having trouble getting something that should be pretty simple working. I am trying to do a simple ping test from a host (that's running zabbix agent) to an external host. In my zabbix_agentd.conf file I have setup a UserParameter such as:

UserParameter=vpnPing[*],fping $1 |grep -c alive

My fping permissions are as such:

# ls -l /sbin/fping
-rwsr-sr-x. 1 root zabbix 52904 Aug 5 2019 /sbin/fping

If I run the zabbix_agentd test I get (fake ip listed for example purposes)

# zabbix_agentd -t vpnPing[123.456.78.901]
vpnPing[123.456.78.901] [t|1]

So that seems to work. When I go to the zabbix UI and look at the latest data I see:

2020-06-04 17:55:30	sh: /usr/sbin/fping: Permission denied
0

The interesting this is the 0 at the bottom. I've also seen it be 1 at times. That sounds like something is working, but I don't get why I get the permission denied. Also when I look at the audit log I see:

I have the Item in Zabbix configured as Type: Zabbix agent If I try:

zabbix_get -s [my_zabbix_server_ip] -k vpnPing[123.456.78.901]

it does timeout (not sure why as I can ping it just fine normally): zabbix_get : Timeout while executing operation But not sure that last part with zabbix_get is relevant b/c the checks to seem to be getting back to the zabbix server but it just says permission denied. I've been struggling with this for a while now and hoping someone can help me out?

This item has been configured according to the documentation https://www.zabbix.com/documentation/6.4/en/manual/config/items/itemtypes/ssh_checks . Actually it seems to work, except that the output of /bin/hostname is lost. It doesn't show up in the item history, and Zabbix' built in test doesn't show the hostname either. If I login as user "zabbix" on the server and try "ssh il06 /bin/hostname", it returns "il06.example.com", of course. Zabbix server and agent are running on Debian 12, using the most recent Debian packages for Zabbix 6.4 found on https://www.zabbix.com/download . libssh on the server is Debian's version 0.10.6. Openssh on the peer is version 9.7. Did I miss something here? Every helpful hint is highly appreciated. PS: Of course I checked Zabbix' bug tracker for similar problems. The Zabbix server log doesn't indicate any problems. either. I also tried to cut off the newline using "echo -n /bin/hostname"

I want to setup email notification using zabbix. When I click _Test_ I get notification > Access denied to remote resource: Remote access denied: 501 My SMTP config: - smtp.office365.com - port : 587 - connection security : STARTTLS - username : myemail@domain.com - password : (redacted) When using GMail I get same notification.

I am trying to install zabbix-agent2 as mentioned in this link agent 2 is available in pre-compiled Zabbix packages. I ran > rpm -Uvh > https://repo.zabbix.com/zabbix/5.4/rhel/8/x86_64/zabbix-release-5.4-1.el8.noarch.rpm Then search for Zabbix-agent2 using yum and it shows available. However, when I try to install using > Sudo yum install zabbix-agent2 It shows Error: Package: zabbix-agent2-5.4.9-1.el8.x86_64 (zabbix) Requires: libc.so.6(GLIBC_2.28)(64bit) How can I resolve this? Is there any alternative way to install it?

I have an issue with the conversion (migration) from zabbix 6.0 to zabbix 6.2. I have a playbook in Ansible to automatically add a host to zabbix with some host_groups and Templates predefined which worked on Zabbix 6.0 but in 6.2 zabbix added the Template_groups and now the playbook complains that it can't find the templates anymore. Here is a part of the playbook:

- name: ZABBIX - Create or update host
  local_action:
    module: community.zabbix.zabbix_host
    server_url: https://monitor.localdomain 
    login_user: "a*******a"
    login_password: "S*********************y"
    host_name: "{{ ansible_hostname }}"
    visible_name: "{{ ansible_hostname }}"
    tls_psk_identity: "{{ ansible_hostname }}"
    tls_accept: 2
    tls_connect: 2
    tls_psk: "{{ psk.stdout }}"
    host_groups:
      - Linux servers
    link_templates:
      - Template OS Linux
      - Template YUM Updates
    status: enabled
    state: present
    inventory_mode: automatic
    interfaces:
      - type: 1
        main: 1
        useip: 1
        ip: "{{ ansible_default_ipv4.address }}"
      - type: 2
        main: 1
        useip: 1
        ip: "{{ ansible_default_ipv4.address }}"
        details:
          community: "{$SNMP_COMMUNITY}"
          version: 2
    proxy: "ZabbixProxy"
  vars:
    ansible_python_interpreter: "/usr/bin/python3"
  tags:
    - zabbix-agent

This worked perfectly on 6.0 and added the servers to the host_group Linux Servers and added the templates OS Linux and YUM updates with no issue. Now in 6.2 it complains that it can't find the templates, and if I outhash the templates it complains that it can't find the host_group. When I outhash that it complains that it has to have at least 1 host group.... :| I tried all combinations of templates, as the templates are now in the template group: "Templates/Operating Systems" I even added a template_groups: section in the playbook as that is a valid field in rust, but apparently it is not for ansible as now it complains on a invalid module found. How do I change/add the templategroup the correct way...? Thanks for reading and thinking along with me.

Issue presentation: - Environment: Debian (bullseye) based distro (proxmox VE) on top of ZFS - Action: Kernel update from 5.15.74-1 to 5.19.17-1 - Consequence: Increment of HDDs disk read request waiting time

I have a zabbix instance showing that the property "Disk read request avg waiting time (r_await)" has increased in a x2 - x3 factor after updating the kernel, from below 20 ms to more than 40 ms. In the machine I have 3 SSD, all of them unaffected; and 3 HDD, all of them affected by this issue in a similar way. Writing waiting time on HDD it's also unaffected (avg = 0.75 ms). If I run a read intensive process like if=/dev/sdx..., then the waiting time of the disk it's reduced to 2-3 ms. So the question are: - Why I have such high read request waiting time on all my HDD? It has increased after the kernel update, but before it was already way higher than HDD write waiting time (near 20 ms avg vs 0.75 ms avg) - Why it's reduced to 2-3 ms when doing intensive reading? Why it's still 3 times higher than write wait time? Best regards.

I want to add item/trigger to Zabbix to check that some server A can send mails via mail server B (SMTP relay) **without sending on real/fake email** and I haven't a problem with firewall/iptables rules and postfix rules. Mail service belongs to me and I use Postfix / CentOS 7. How can I do it? I know that I can send real mail via mailx or netcat, the command will be something like this: echo "Test message" | mailx -v -r "from@some.com" -s "Some subject" -S smtp="mail-server-b.com:25" to@some.org and parse result but I don't want to do it.

i've been trying to install those packages required for installing zabbix on centos 9 stream but i came to a problem. I've been following this guide for installing zabbix on official webpage here: https://www.zabbix.com/download?zabbix=6.2&os_distribution=centos&os_version=9&components=server_frontend_agent&db=mysql&ws=apache but i got stuck on this packages instalations: **dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent** My error is: Problem: package zabbix-web-deps-6.2.4-release1.el9.noarch requires zabbix-web = 6.2.4-release1.el9, but none of the providers can be installed - cannot install both zabbix-web-6.2.4-release1.el9.noarch and zabbix-web-1:6.0.8-1.el9.noarch - package zabbix-apache-conf-6.2.4-release1.el9.noarch requires zabbix-web-deps = 6.2.4-release1.el9, but none of the providers can be installed - package zabbix-web-mysql-1:6.0.8-1.el9.noarch requires zabbix-web = 1:6.0.8-1.el9, but none of the providers can be installed - cannot install the best candidate for the job Only thing i did on my VM before i ran this command was disabling selinux and firewalld and dnf update. Should i install mariadb or php server before i run this command? I am kinda new and still learning and i haven't been able to find any solution on my own. Thanks very much for help.

I'm trying to get a JSON document with the top 5 processes by memory. This JSON I want to send to Zabbix and draw the top 5 processes by memory. I get the top 5 processes by memory by the following command: ps axho comm --sort -rss | head -5 node mongod kubelet dockerd systemd-journal How to convert the output of ps+head to JSON with key {#PROCNAME} to get this structure:

{
  "data": [
    {
      "{#PROCNAME}": "node"
    },
    {
      "{#PROCNAME}": "mongod"
    },
    {
      "{#PROCNAME}": "kubelet"
    },
    {
      "{#PROCNAME}": "dockerd"
    },
    {
      "{#PROCNAME}": "systemd-journal"
    }
  ]
}

I'm configuring Zabbix to monitor our servers. Zabbix is new to me. It is up and running, and monitoring works for some services. One of our Centos servers has http running, so it seems logical to monitor that. I've added the "Template App HTTP Service" to the host. I used all default settings, didn't change anything. Now Zabbix reports that this service is down. The httpd service is running however, and I can open webpages. How can I get Zabbix to monitor the HTTP service normally?

how can I save item's output in macro and use it in another item ? i mean reguler item not LLD . for example : I want to get some port app dynamicly and check tcp conection

My question is about zabbix traps with SNMPv3 and snmptrapd service using **zabbix_trap_receiver.pl**. I have a switch on which I enabled SNMPv3 only, so the switch has no SNMPv1/2c **rw** or **ro** communities configured, and I was able to add it as a host on zabbix after a long journey modifying existing SNMPv2 templates. In zabbix documentation in **snmptrapd.conf** there is a couple of lines added as shown here to enable SNMP traps: authCommunity execute public perl do "/usr/bin/zabbix_trap_receiver.pl"; My questions: - What is the meaning of authCommunity execute public - I don't have **public** community configured, will snmptrapd service be able to decrypt SNMPv3 traps because on wireshark I had to define SNMPv3 credentials for it to be able to show me traps packets content? - If not, how can I configure it in **snmptrapd.conf** so that the perl script can read these traps from SNMPv3? - On wireshark, why does it say SNMPv2c trap, although it is encrypted as SNMPv3, I am lost here? - Please explain to me how traps work in when SNMPv2 isenabled and when SNMPv3 is enabled? **Edit** I also tried the following createUser -e SHA AES authUser log,execute perl do "/usr/bin/zabbix_trap_receiver.pl"; But no luck

I have some sudo rules setup for many (virtual) servers (mostly debian) to be used by zabbix scripts: zabbix ALL=NOPASSWD: /etc/init.d/exim4 restart The zabbix-agent and sudo configuration file (/etc/sudoers.d/zabbix-agent) is distributed via ansible, and is the same for all servers. However, on some servers, sudo asks for a password. On others, it does not. It is the same whether I run the command using zabbix, or locally: # sudo -u zabbix sudo /etc/init.d/exim4 restart Sometimes, it works and sometimes it asks for the password. I looked into it, and the obvious answer that there is a different rule for the zabbix user in the sudo config is not true. What other factors could result in the system asking for a password anyway?
