no vmstat data for 8 hours on weekdays?
Hello, all.
I've got something odd going on...I have one AIX 5.3 system for which the CPU Utilization (vmstat) graph is blank from 9AM to 5PM, only on weekdays. None of my other AIX systems (5.3 or 6.1) are displaying the same behavior.
I've installed the same Hobbit client on all of my AIX instances. The vmstat processes are running as they should, and all of the other graphs in the trends area get data all day long.
I've already looked and I have no "TIME" options set for this specific for this server in either the localclient.cfg file on the server nor the analysis.cfg on the Xymon server...in fact, other than this system's entry in the hosts.cfg, there is no mention of this system in any config file EXCEPT hosts.cfg.
Any thoughts would be appreciated.

Odd. Is the blank section EXACTLY (within 5 minutes) between 9am and 5pm, or just approximate?
Are you getting updates for your client data? Check out the [vmstat] section both inside and outside of the 9-5 range, and see if they look different.
Perhaps during business hours, there is a process that runs, or a general increase in load, that increases the numbers in the vmstat output, such that the columns are no longer aligned the same. I know that there is at least one Xymon client data parser that fail if the columns aren't aligned as expected (procs, perhaps).

This morning 9:15AM and hadn't resumed graphing vmstat data as of 5:07 when I left the office (will need to check when I get hone tonight or in the morning at the office, but I'm expecting the data to have started around 5:15PM).
Over the weekend, there were no breaks in data graphing.
I'll have to also look at a continuous vmstat output, just in case.

Ok…I can confirm that the graph started again at the 5:15PM mark, yesterday.
Does the parser look for specific column placement? If it does, shouldn’t it look for white/blank space(s) as data column delimiters?
In the meantime, I’m capturing a vmstat run, now, and will capture another if/when the graphing ceases again…I’m curious, though…the vmstat command line appears to be “vmstat 300 2”…that’s 300 captures in 2 second intervals (10 minutes worth of captures). As there are two vmstat processes running at any time, with a secondary command of “mv /usr/local/hobbit/tmp/hobbit_vmstat.PID /usr/local/hobbit/tmp/hobbit_vmstat.HOSTNAME”, is there a chance that the files are clobbering each other when they’re moved? Granted, each process have start times at 5 minute intervals, but I’m wondering.

I’m also noticing that even though I’m getting data in my graphs, right now, I’m not seeing much of anything in the actual vmstat output files in /usr/local/hobbit/tmp.

And, again, after the 9AM graph update, nothing going into the graphs. The output columns don’t seem to be drifting any more than they were before the 9AM time frame, as I’m watching the vmstat output on my screen.

FWIW, I’m attaching vmstat output that ends pre-dropoff and another that starts pre-dropoff. With any luck, something will stand out.
Xymon server is 4.3.10, Hobbit client on AIX is 4.2.0, if that makes any difference.

And, again, after the 9AM graph update, nothing going into the graphs. The output columns don’t seem to be drifting any more than they were before the 9AM time frame, as I’m watching the vmstat output on my screen.

I’m also noticing that even though I’m getting data in my graphs, right now, I’m not seeing much of anything in the actual vmstat output files in /usr/local/hobbit/tmp.

Ok…I can confirm that the graph started again at the 5:15PM mark, yesterday.
Does the parser look for specific column placement? If it does, shouldn’t it look for white/blank space(s) as data column delimiters?
In the meantime, I’m capturing a vmstat run, now, and will capture another if/when the graphing ceases again…I’m curious, though…the vmstat command line appears to be “vmstat 300 2”…that’s 300 captures in 2 second intervals (10 minutes worth of captures). As there are two vmstat processes running at any time, with a secondary command of “mv /usr/local/hobbit/tmp/hobbit_vmstat.PID /usr/local/hobbit/tmp/hobbit_vmstat.HOSTNAME”, is there a chance that the files are clobbering each other when they’re moved? Granted, each process have start times at 5 minute intervals, but I’m wondering.

I’ve got something odd going on…I have one AIX 5.3 system for which the CPU Utilization (vmstat) graph is blank from 9AM to 5PM, only on weekdays. None of my other AIX systems (5.3 or 6.1) are displaying the same behavior.
Odd. Is the blank section EXACTLY (within 5 minutes) between 9am and 5pm, or just approximate?
Are you getting updates for your client data? Check out the [vmstat] section both inside and outside of the 9-5 range, and see if they look different.
Perhaps during business hours, there is a process that runs, or a general increase in load, that increases the numbers in the vmstat output, such that the columns are no longer aligned the same. I know that there is at least one Xymon client data parser that fail if the columns aren't aligned as expected (procs, perhaps).Friday of last week, on the 9AM mark. This morning 9:15AM and hadn't resumed graphing vmstat data as of 5:07 when I left the office (will need to check when I get hone tonight or in the morning at the office, but I'm expecting the data to have started around 5:15PM).
Over the weekend, there were no breaks in data graphing.
I'll have to also look at a continuous vmstat output, just in case.

Some parsers don't use whitespace delimeters, but instead use column position. But I don't know if the vmstat parser does the same.
vmstat command line appears to be “vmstat 300 2”…that’s 300 captures in 2
second intervals (10 minutes worth of captures).
No, I think you'll find that it's two captures in 300 second intervals. The first sample is the total/average since last boot, and the second sample is the total/average since the first one. The first sample is discarded.
As there are two vmstat processes running at any time, with a secondary command of “mv /usr/local/hobbit/tmp/hobbit_vmstat.PID /usr/local/hobbit/tmp/hobbit_vmstat.HOSTNAME”, is there a chance that the files are clobbering each other when they’re moved?
Yes, perhaps. I only have one vmstat command running at any one time. You might try killing both off and see what happens.

I just checked the code, and I think the vmstat parser (in do_vmstat.c function do_vmstat_rrd()) splits on whitespace, thus uses column number rather than column position. So this shouldn't be a problem for you.
Ok...that's good news on one front...I'd love to know what the heck is going on then.
I'm going to stop the hobbit client, kill any lingering vmstat processes and then restart the hobbit client and see what happens.

Good to know...I was trying (unsuccessfully) to compile the 4.3.10 client for AIX, in case it was the client side.
On the other side...I did stop the client, killed any remaining vmstat processes and started the client back up. Initially, only one vmstat process was running, and then eventually there were two at any given time, again. They kick off every 5 minutes, outputting to a vmstat file tied to that process' PID (hobbit_vmstat.<hostname>.PID), and at the end of the run, the PID specific vmstat file is supposed to be renamed to hobbit_vmstat.<hostname>. The one thing I notice is that I never see a file hobbit_vmstat.<hostname>...even now, while there is still data actually being reported in the graph (it's only 7:44AM at present), there is no vmstat file without the PID as part of the file name present. Not that I think that is the problem.
Is there anything I can do to increase verbosity in the client and/or server logging to determine if there's some sort of communication issue (or lack thereof)?

Nice one. Pretty sure it would be MAXMSG_CLIENT, which relates to the client messages. I have this set to 2048 on my server because I have some particularly fast-moving log files I want to monitor on a couple of my servers.
Rather than increasing the limit, you might want to find out why the client message is so large and try to reduce the size if you can. Perhaps the server is logging heeeeaps of messages into a logfile that's being monitored. Have a browse through the client data and see if there's one section that's really big and can probably be adjusted or eliminated.
$ xymoncmd xymon localhost 'clientlog name-of-client' | less
If it's log data, and you don't actually report on log messages, you might consider removing the "log:" entry from client-local.cfg on the Xymon server - either from the [aix] section, or (if it exist) from the [name-of-host] section.
Or you can have the client put a cap on the size of log data being sent back in its client message by adjusting the "log:" entry in the file client-local.cfg on the server. This limit is fetched by the client from the server after it reports its client data. So an adjustment on the server can take up to 10 minutes to be honoured by the client. The default for AIX syslog.log is 10k, so it's unlikely that this alone could push your client messages beyond 512k.

I think Mike said yesterday that is was his "procs" section that was causing the client to generate oversized client message. This test precedes the vmstat test in xymonclient-aix.sh
