Very simple example munin plugin
#!/usr/bin/env python
import os
from munin import MuninPlugin
class TmpFileCount(MuninPlugin):
title = "Number of Files in /tmp"
args = "--base 1000 -l 0"
vlabel = "files"
scaled = False
category = "system"
def fields(self):
warning = os.environ.get('files_warn', 10)
critical = os.environ.get('files_crit', 120)
return [("files", dict(
label = "files",
info = 'The number of files in /tmp',
type = "GAUGE",
min = "0",
warning = str(warning),
critical = str(critical)))]
def execute(self):
dircount = len(os.listdir("/tmp"))
print "files.value %s" % dircount
