How do I view all syslog entries

How do I view all messages in the syslog? I am looking for messages that my program is generating that I have tagged with `[pistreaming] so I can find these messages usign grep` sudo more /var/log/syslog | grep -i pistreaming and I get output like this: Feb 23 19:31:49 opcrd logger: Starting pistreaming service... Feb 23 19:31:52 opcrd [pistreaming] Initializing websockets server on port 8084 Feb 23 19:31:52 opcrd [pistreaming] Initializing HTTP server on port 8082 Feb 23 19:43:21 opcrd logger: Starting pistreaming service... Feb 23 19:43:24 opcrd [pistreaming] Initializing websockets server on port 8084 Feb 23 19:43:24 opcrd [pistreaming] Initializing HTTP server on port 8082 Feb 23 19:43:24 opcrd [pistreaming] Initializing broadcast thread Feb 23 19:43:24 opcrd [pistreaming] Starting recording Feb 23 19:43:24 opcrd [pistreaming] Starting websockets thread Feb 23 19:43:24 opcrd [pistreaming] Starting HTTP server thread Feb 23 19:43:24 opcrd [pistreaming] Stopping recording Feb 23 19:43:25 opcrd [pistreaming] Waiting for broadcast thread to finish but, if I don't `grep`, these messages don't seem to show up in the log; what am I doing wrong?
