Hey all,I'm trying to configure an exec plugin and have the results sent over the network plugin to my central collectd server. All instances are running 4.10.2.
Here's my configuration element:
<Plugin exec>
Exec "operator" "/bin/cat" "/var/log/mailstats"
</Plugin>
Now, when run in debug mode, I see this:
Aug 21 14:09:48 smtp01 collectd[6126]: utils_cmd_putval: handle_putval
(fh = 0xb7f134c0, buffer = PUTVAL
smtp01.osg.ufl.edu/smtp-stats/kbytes_from N=264468);
Aug 21 14:09:48 smtp01 collectd[6126]: utils_cmd_putval: handle_putval
(fh = 0xb7f134c0, buffer = PUTVAL smtp01.osg.ufl.edu/smtp-stats/msgs_to
N=3604);
Aug 21 14:09:48 smtp01 collectd[6126]: utils_cmd_putval: handle_putval

smtp01.osg.ufl.edu/smtp-stats/kbytes_to N=293286);

Aug 21 14:09:48 smtp01 collectd[6126]: utils_cmd_putval: handle_putval
(fh = 0xb7f134c0, buffer = PUTVAL
smtp01.osg.ufl.edu/smtp-stats/msgs_discarded N=57);
Aug 21 14:09:48 smtp01 collectd[6126]: exec plugin: exec_read_one:
Waiting for `/bin/cat' to exit.
Aug 21 14:09:48 smtp01 collectd[6126]: exec plugin: Child 6381 exited
with status 0.
Those buffers are the lines of the file in /var/log/mailstats (all pretty plain PUTVALs).
All other plugin data goes correctly to the central collectd server except this one. I don't normally do exec plugins on the remote systems -- usually I only run exec on the central collectd server.
On other Exec plugins, I see plugin_dispatch_values and "uc_insert: Added foo to the cache" after my exec'd process exits. But I don't see those for this particular configuration I'm debugging.
Any ideas for next steps to debug? I've turned up the debug log level on the central server and I never see anything about the plugin data I'm trying to get sent.
