ingler

ingler is a system monitoring tool. It runs commands periodically, and syslog's these stdout.

How does it work?

ingler repeats the following sequence periodically.

1. scans the install directory to find executables which have the prefix of "ingler." ("ingler" with one dot, such as "ingler.cputemp").
2. executes all of them.
3. sends STDOUT of these to syslog.

For example

Assume that you have the following modules

• /usr/local/bin/ingler.cpufreq
• /usr/local/bin/ingler.diskusage

ingler executes these two in each period. If ingler.diskusage outputs to STDOUT:

usage=90%

it will be syslog'ed, for example:

Jul 23 02:09:29 <daemon.info> hostname ingler[13138]: diskusage: usage=90%

ingler does not

ingler does not notify any incidents. All ingler does is only monitoring. Notification is the roll of any other systems.

ingler has modules of

• ingler.cputemp: the module to monitor CPU temperature
