I have an issue with custom script using exec plugin. From shell the script works well and nothing useful in /var/log/collectd.log.
LoadPlugin logfile
<Plugin logfile>
LogLevel info
File "/var/log/collectd.log"
Timestamp true
PrintSeverity true
</Plugin>
How can I debug/troubleshoot it? In the doc I found an example
-> | PUTVAL "testhost/interface/if_octets-test0" interval=10 1179574444:123:456
<- | 0 Success
But how can I run it, how can I pass my PUTVAL to collectd? The collectd does not listen any port (all the other plugins work well and send data to graphite).
Just to be clear: the problem is not to see the generated string but to make sure the particular string will be accepted.
Thank you.
p.s. the particular issue: the script returns dozens of values but one of them only get to graphite.
