[mrtg] external script no longer functions...

[Evert Meulie]

Hi everyone!

The following mystery: I have in my mrtg.conf the following lines:
[snip]
Target[conncount_192.168.100.1]: `/usr/local/bin/connection_poll_ssh`
Options[conncount_192.168.100.1]: gauge,growright,nopercent,noo
Title[conncount_192.168.100.1]: Connection count
MaxBytes[conncount_192.168.100.1]: 20000
PageTop[conncount_192.168.100.1]: <H1>Connection count</H1>
LegendO[conncount_192.168.100.1]: Connections
LegendI[conncount_192.168.100.1]: Connections
YLegend[conncount_192.168.100.1]: connections
ShortLegend[conncount_192.168.100.1]: &nbsp;connections
[/snip]

This script returns 2 values: first the actual number, and then a 0, like:
257
0


This has worked fine so far, and still works, but only when I call the
script manually.

In mrtg.conf now all it does is generate the following errors in the
mrtg-log:
2004-12-15 08:50:24 -- Started mrtg with config '/etc/mrtg.conf'
2004-12-15 08:50:47 -- WARNING: Could not get any data from external
command '/usr/local/bin/connection_poll_ssh'
Maybe the external command did not even start. (Illegal seek)

$target->[1]{$mode} ' did not eval into defined data

The only change I have made to my mrtg.conf is moving part of it
(relating to other hosts and below this poll in the original log) to a
separate file which I include with 'Include: mrtg-users.conf'


What did I do wrong here...?
