NAME
plugmon
SYNOPSIS
plugmon [options]
DESCRIPTION
plugmon is system monitoring utility with minimal configuration requirements.
The following facilities are monitored:
filesystems, kernelmessages and daemons.
Filesystems
Filesystems checked are all mounted filesystems. Each filesystem is checked for the usage in percent of total available blocks and inodes. Events are sent for each 10% boundary passed as well as for each percentage point above 90%. Any new mounted filesystems are also detected. Kernelmessages
Kernelmessages are read from the kernel ringbuffer in a way that does not disturb other programs reading this buffer (ie klogd). Only messages categorized as warning or worse are sent as events. Daemons
Daemons are detected by checking all processes with a TCP listening port active. Also considered as daemons to be checked are running processes that fits some heuristics:
- Parent process is no 1.
- The process has no controlling tty.
Optional configuration file
Plugmon does not need a configuration file to work but a few things may be tuned with a configuration file (monitor.conf). See separate manpage for monitor.conf. Features
Plugmon detects any change to the configuration file and will reload it at that time. Plugmon also detects if its own binary has been changed and in that case will reexecute itself while keeping all information gathered upto that point in time.
