[Xymon] leaking memory, alerts.cfg problems

[Carl Inglis]

From the man page:

NOCOLUMNS:column[,column]
Used to drop certain of the status columns generated by the Xymon client. column is one of cpu, disk, files, memory, msgs, ports, procs. This setting stops these columns from being updated for the host. Note: If the columns already exist, you must use the xymon<http://uk-netmon/xymon/help/manpages/man1/xymon.1.html>(1) utility to drop them, or they will go purple.

That suggests to me that your “NOCOLUMNS: telnet” is invalid – makes me wonder if it’s triggering that test as a result of that .default. entry.

Be interested to see what you find.

Regards,

Carl

@Jeremy,

This is a bug in Samba.  Refer: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1257186

This is entirely unrelated to Xymon.

Terrific, thank you.


If you don't have "telnet" listed for a host/device in hosts.cfg, or in the ".default." entry, then Xymon should not include it in its service checks.

 OK, this is where I'm struggling.  We have a separate host group for our switches:


group-sorted UFIRST Switches
0.0.0.0         .default.       # NOCOLUMNS:telnet
192.168.0.5      SWITCH1        # ssh

But originally had had:

192.168.0.5      SWITCH1        # telnet

We followed the instructions for purging the history:

xymon 127.0.0.1 "drop SWITCH1 telnet"

But we still received alerts.
red  Wed Sep  3 09:26:38 2014 telnet NOT ok
Service telnet on SWITCH1 is not OK : Service unavailable (Connection refused)
Seconds: 0.00
So I tried filtering it in the alerts.cfg:


HOST=%* SERVICE=%*
        MAIL tres at company.local<mailto:tres at company.local> EXSERVICE=telnet

But now we aren't receiving any alerts at all.

To verify it's not an email settings:

mail -s "Test Email" tres at company.local<mailto:tres at company.local> < /dev/null

Which succeeds.

The only part I did not mention is that some of our hosts were renamed from lowercase to uppercase for aesthetics.
