leaking memory, alerts.cfg problems
That suggests to me that your “NOCOLUMNS: telnet” is invalid
How so? My usage matches the manpage, no?
The manpage says “column is one of cpu, disk, files, memory, msgs, ports, procs.” – it doesn’t mention “telnet” as an option to drop.
Regards,
Carl

The manpage says “*column* is one of *cpu*, *disk*, *files*, *memory*, *msgs*, *ports*, *procs*.” – it doesn’t mention “telnet” as an option to drop.
Well, then the manpage should be updated.
Here is the page normally:
And here is the page with "0.0.0.0 .default. # NOCOLUMNS:telnet" added.
To entertain the suggestion, I've commented out the .default. line too but still no alerts... I'm not sure where else to look.
Maybe I’m confused, but what’s the point of using NOCOLUMMS for something that’s not one of the statuses that is sent by the client? If you want to omit telnet, simply don’t list it in hosts.cfg for the host. If you want to drop an existing column, look into “Tips and Tricks” under the Help menu, and navigate to “How do I delete a test status?”.
NOCOLUMNS is for something that the client will continue to send, and you can’t turn off, but don’t want to display.

@Ribeiro,
Thanks kindly for the reply. Please see my responses below.
Maybe I’m confused, but what’s the point of using NOCOLUMMS for something that’s not one of the statuses that is sent by the client?
I agree. I mentioned in my second post that I ran the "drop" statement per instructions. I've done this several time, but telnet keeps coming back. Hiding it using NOCOLUMNS is the only way to keep the page from going purple.
If you want to omit telnet, simply don’t list it in hosts.cfg for the host.
As aforementioned, we don't list in in hosts.cfg, we list # ssh instead. I'm not sure why it keeps coming back.
If you want to drop an existing column, look into “Tips and Tricks” under the Help menu, and navigate to “How do I delete a test status?”.
As aforementioned, we did this.
NOCOLUMNS is for something that the client will continue to send, and you can’t turn off, but don’t want to display.
Since the client is a switch, I'm not sure we have the ability to alter anything from the "send" side of the fence. Let me know if this assumption is incorrect.
@Carl,
I just saw your reply come in. I'll try your recommendations now.

@Carl,
Thank, I believe that corrected the lingering telnet. It has not reappeared, thank you.
But I'm still not receiving alerts. We've intentionally left SSH disabled on this switch to trigger an alert, but emails don't seem to be going through.
What is the command to trigger a test email from xymon? I found this in the archives:
$ xymoncmd xymon_alert --test SWITCH1 ssh
But I get this:
2014-09-10 11:14:01 Using default environment file /usr/lib/xymon/client/etc/xymonserver.cfg 2014-09-10 11:14:01 execvp() failed: No such file or directory
I assume xymon doesn't stop sending alerts after a timeout period, right? We chose to use the SSH service since it doesn't affect our environment. We can add a fake hostname/ip as well. I fear may have something misconfigured since alerts won't go through at all.

This is a problem. Xymoncmd couldn’t find xymon_alert. So it’s not in your path, you need to give the full path.

No. xymon sends alerts by what you define for it to send. There are no alerts by default.

As Paul pointed out, use “xymond_alert” rather than “xymon_alert”. One of the most useful debug tools I’ve found for alerting is:
Add --cfid to the CMD in the [alerts] section of tasks.cfg
It means that when you *do* get your alerts working, you’ll get the line number of test line that fired in the subject of the message; this allows you to identify exactly which rule triggered the message.
Good luck. ☺

AH! You have a purple status – looks to me like the “drop” command didn’t work.
Perhaps try dropping it with the hostname in lower case?
I’ve found in the past that drop can be temperamental and I’ve on occasion ended up dropping the whole host to check that I’ve got it right.
Regards.
Carl
