Issue with xymon-rclient.sh
list Becker Christian
Hi to the list,
working with xymon since 2008, still using it.
Now I was in the situation to include a LinuxMint machine (with desktop environment), using Jeremy’s xymon-rclient.sh 0.6.1 to monitor this thing.
After setting up the ssh-based authentication and waiting a couple of minutes, the data of this LinuxMint machine came up and appeared in Xymon.
Other than other machines i’m pulling with xymon-rclient.sh, the CPU state of this machine became red immediately.
It seems to me that the Load Average of the LinuxMint machine is interpreted wrong: when looking in Xymon, it tells me a Load Average of 60.00, while looking to the LinuxMint machine, seeing it’s Load Average at 0.6.
What could be wrong? The LinuxMint machine is running LinuxMint 22.1 with it’s lates updates.
These are the locales used by the LinuxMint machine:
LANG=en_US.UTF-8
LANGUAGE=en_US
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC=de_DE.UTF-8
LC_TIME=de_DE.UTF-8
LC_COLLATE="en_US.UTF-8"
LC_MONETARY=de_DE.UTF-8
LC_MESSAGES="en_US.UTF-8"
LC_PAPER=de_DE.UTF-8
LC_NAME=de_DE.UTF-8
LC_ADDRESS=de_DE.UTF-8
LC_TELEPHONE=de_DE.UTF-8
LC_MEASUREMENT=de_DE.UTF-8
LC_IDENTIFICATION=de_DE.UTF-8
LC_ALL=
Yes, they are mixed….
We’ve a few other linux client machines running “non-server-linuxes” (i.e. RaspberryPi running Raspberry PI OS) which are reporting fine using xymon-rclient.sh.

Christian

Looking at the server side code, the cpu load average for a linux client is actually extracted from the [uptime] section, not the [top] section, which surprised me a little. (i.e. the sections as generated in the output of /usr/lib/xymon/client/bin/xymonclient-linux.sh) The [uptime] section is the output of just running "uptime". The server code looks for the string "load average: " or "load averages: ", then after that looks for either of the patterns "FLOAT, FLOAT, FLOAT" or "FLOAT FLOAT FLOAT". The middle float from that list is then reported as the CPU load. Christian: what does the output of "uptime" look like on your client? Adam

Christian,
Looking at xymon-rclient.sh, it will grab the load average from the "top" command. I assume for your configuration that it is using the xymonclient-linux.sh script to collect the data. If so, it runs "$TOP -b -n 1" and the line near the top that has the load average is used. $TOP would be defined in your xymonclient.cfg file for the client.
What does the head of "top -b -n 1" look like on your system?

Seems like a locale issue. The decimal point is a comma so the server ignores the leading zero.

It really was a locale issue. After applying en_US.UTF-8 as locale, rebooting the LinuxMint machine, and another run of xymon-rclient.sh, the CPU check is fine within Xymon.

Seems like a locale issue. The decimal point is a comma so the server ignores the leading zero.

Adam,
thx for your help.
The output of uptime is:

Nearly at the same time I get this in Xymon:

Looking at the server side code, the cpu load average for a linux client is actually extracted from the [uptime] section, not the [top] section, which surprised me a little.
(i.e. the sections as generated in the output of
/usr/lib/xymon/client/bin/xymonclient-linux.sh)
The [uptime] section is the output of just running "uptime". The server code looks for the string "load average: " or "load averages: ", then after that looks for either of the patterns "FLOAT, FLOAT, FLOAT" or "FLOAT FLOAT FLOAT". The middle float from that list is then reported as the CPU load.
Christian: what does the output of "uptime" look like on your client?

I think it's LC_NUMERIC that matters here. I think the underlying bug here is that the server code uses sscanf() to parse uptime, and I guess that's not properly locale-aware. A possible workaround if you want to maintain your locale comes from noting that xymonclient-linux.sh just runs "uptime" which thus implicitly uses whichever "uptime" is first on your path. On my systems that's /usr/bin/uptime, so I could provide /usr/local/bin/uptime with: #!/bin/bash LC_NUMERIC=C /usr/bin/uptime to just run uptime with the expected locale. Or, I see multiple sscanf() calls in xymond_client.c so maybe there are similar bugs lurking elsewhere... So, you could edit the xymonclient-linux.sh script sent by xymon-rclient.sh and put LC_NUMERIC=C (and perhaps other locale variables if necessary? Or just LC_ALL?) at the top of the script.

That’s by far my favourite solution, because then for me there’s no need to change the locales on the LinuxMint system….

Another option is to add an env() to the RCLIENT settings in hosts.cfg, such as:
127.0.0.42 cb-m340c # "RCLIENT:cmd(ssh -T user@%{H}),env(LC_NUMERIC=C)"
