check-log

check-log

Description

Checks a log file using a regular expression.

Setting

[plugin.checks.log]
command = "/path/to/check-log --file=/path/to/file --pattern=REGEXP --warning-over=N --critical-over=N"

Using glob

You can check multiple files by using globs (and zsh extented globs by mattn/go-zglob) in --file option. For example, --file=/tmp/some.log_* will check all of /tmp/some.log_1, /tmp/some.log_2, and so on.

And since command in mackerel-agent.conf will be parsed by shell (in *nix /bin/sh -c, in Windows cmd /c), specifying glob like --file /tmp/some.log_* does not work as expected. It will be expanded like --file /tmp/some.log_1 /tmp/some.log_2, so it will check only /tmp/some.log_1.

Therefore, when you want to check multiple files, use --file=<glob>, not --file <glob>.
