Solaris 10 swap not showing on memory alert correctly?
by david.gore＠verizon.com 28 Aug '13

28 Aug '13

Just a heads up. So unfortunately, I am going to have to try something different. One of my xymon scripts got hung and launched every 5 minutes and filled /tmp and swap was consumed as reported by swap -s but not swap -l. Production processes could not allocate memory and Xymon was blissfully unaware reporting 0 swap used and memory Ok. Here is a message from the log (/var/adm/messages). Of course, we added this message to our alert list. Aug 24 15:10:24 ourHost genunix: [ID 470503 kern.warning] WARNING: Sorry, no swap space to grow stack for pid 19464 (ksh) swap as shown by Xymon at 0 used memory less than 50% of 128G used Xymon client 4.3.10 Xymon server 4.3.12 Server monitored is a SUN T5240 running Solaris 10 Ok, I just realized this is a bit odd isn't it? Out of swap but plenty of physical memory left. Time to Google.

That link appears to only apply to Zones as I can see the numbers roughly adding up similarly on at least one of my Solaris machines allocated as a zone. Here is how I think the numbers add up on my non-zone traditional machine. prtconf|grep Memory Memory size: 24576 Megabytes Physical memory: 25,769,803,776 bytes swap -s total: 18615728k bytes allocated + 3112800k reserved = 21728528k used, 32078664k available Converted to bytes: (x1000)total: 18,615,728,000 bytes allocated + 3,112,800,000 reserved = 21,728,528,000 used, 32,078,664,000 available (x1024) 19,062,505,472 + 3,187,507,200 = 22,250,012,672 used, 32,848,551,936 available swap -l swapfile dev swaplo blocks free /dev/vx/dsk/bootdg/swapvol 278,60000 16 73552112 72369616 Let's look at the last two numbers 73,552,112*512 = 37658681344 bytes 72,369,616*512= 37,053,243,392 37,658,681,344 -37,053,243,392 = 605,437,952 == 577M swap used So to answer my own question. I think the first 2 numbers in swap -s represent physical memory. I think the last number is some amount from swap and some amount from physical memory. Some of what's in Vernon's article hints at where it all gets allocated. It would appear that Xymon just subtracts the last two numbers in swap -l to get swap used in megabytes. ~David From: Vernon Everett [mailto:everett.vernon at gmail.com] Sent: Wednesday, June 26, 2013 11:00 PM To: Gore, David W (David) Cc: xymon at xymon.com Subject: Re: [Xymon] Solaris 10 swap not showing on memory alert correctly? Solaris and swap is tricky to nail down, specifically because different commands will report different values, by calculating the values in different ways. You need to choose your commands carefully, depending on what value you need to know. This might help explain things. http://www.f3partners.com/blog/bid/49584/Solaris-Swap-Q-A It all becomes rather fuzzy when you consider what ZFS is doing in your memory. Also, in a zone, all bets are off. Caps in particular, on memory or swap, can completely muddy the water. All the checks within the zone, will show the max available as being the capped value. However when you interrogate the kernel for amount free, it returns what the kernel can see. And the kernel can see everything, because it exists in the global zone. Regards Vernon P.S.

Serial alarm feeds- Now remote client.
by kc6ovd＠gmail.com 27 Aug '13

27 Aug '13

Probably should rename this thread as we are talking the xymon remote client here. I did get log fetch to work with your script, sorta. I added the file in the script to collect and it collects it and posts it to the message column Good. This is with your xymon remote client. but of course it is not processed for alerts, Just collected. So it just needs an entry in analysis.cfg? I might try it but doubt it will work right, as you explain below. I added this to the xymonclient-linux.sh that I use for the hosts I use your script for. Hmmm If I get this other log fetch working I might be able to smash your script with this and make that work. Ok better stick to one thing at a time. Always. echo "[msgs:/var/log/messages]" tail -c 10240 /var/log/messages | egrep -v MARK echo "[msgs:/var/TKLC/log/syscheck/fail_log]" tail -c 10240 /var/TKLC/log/syscheck/fail_log Well this works, in as much as you'll get message lines in your client data, but you'll end up with repeated and skipped messages. So if you alert on the text "WARNING" and it appears in the log, sure you'll get an alert. But if the log gets less than 10k of data appended throughout the day, Xymon will repeat the alert all day. Or if, between one sample and the next, the "WARNING" message and then 10k of log data is added, the second sample won't see the matching message because it always gets the last 10k. These issues are dealt with by the logfetch utility. It keeps state so that it (generally) gives out each log message line exactly once - none is missed and none is repeated. You can handle this yourself, by keeping state of the size of the log file you're watching, and always tailing what's after that size. You also have to detect and handle log rotation. Doable, but lots of trouble. If you can get logfetch to work, then why not use it. Especially as it can give you your (its) config file from client-local.cfg to boot. I remember a nice log utility we had in Big brother. I want to say message.sh and message2.sh or something like that. I remember a config file where you could create alert text triggers, it even took care of multi-line messages. It made sure it kept track of the lines processed. Sean are you lurking? -Kevin

esxi monitoring issues, high cpu load
by mark.rosedale＠gmail.com 27 Aug '13

27 Aug '13

Hello, I'm working on setting up esxi monitoring. We have about 20 machines that we are looking to monitor. I found xymonesxi on sourceforge and got everything up and running. However, if I add more than a few esxi servers the cpu spikes on the xymon box. I'm not getting any errors in the esxi or esx logs. Has anyone else noticed the high cpu load using this check? Is there anything I can do to mitigate the issue? Thanks, mjr

Login Separation
by dschroeter＠corpcomp.com 27 Aug '13

27 Aug '13

I'm migrating from a BigBrother implementation, and merging in some hosts from Zabbix. Both allowed me to set up an area for one of my clients to allow them to see their servers, but no one else's. Does Xymon have that ability? It would be nice to allow them to even put servers into Maintenance mode. If I have to login protect the root site, that's OK by me I just need to give them access, but not to any of the other servers on site. Thanks David

Serial alarm feeds
by kc6ovd＠gmail.com 27 Aug '13

27 Aug '13

Fellow xymoners, I am looking for some ideas on how to monitor some alarm feeds (serial ROP). I have to collect them from the xymon server, The platform involved cannot support a xymon client, I have the collection part down to stream it to a log file. But I want to use the log monitor feature for the clients, so I can build the alerts and post the results under the hosts display on xymon. If it helps here is a typical message: HOSTNAME 13-08-24 06:28:04 CST EAGLE 44.0.4-64.34.24 7879.1056 CARD 5107 INFO SCCP rcvd inv SCMG - bad subsystem SIO=a3 OPC= xxx-xxx-xxx DPC= xxx-xxx-xxx SCMG: MSG TYPE=003 MSG LEN=006 AFTPC= 001-151-001 AFTSS=008 MULT=000 LSN=m209250004 Report Date:13-08-24 Time:06:28:02 ; Any thoughts or a different way to deal with it is welcome. Fresh eyes and ideas help break out of my box. Thanks -Kevin

Feature request?
by Galen.Johnson＠sas.com 26 Aug '13

26 Aug '13

Not sure if this is already possible but since you can "redefine" a host in hosts.cfg, it seems logical that alerts.cfg should be able to key on NAME: and/or CLIENT: instead of just the Host field. Is this something Xymon should already do or already been requested? Does it make sense to do so or am I just smoking crack? =G=

msgcache + standard
by Galen.Johnson＠sas.com 26 Aug '13

26 Aug '13

Hey, Has anyone set up Xymon clients to do both msgcache and standard connections? Anyone know if enabling msgcache and then setting: XYMSRV="0.0.0.0" # IP address of the Xymon server XYMSERVERS="10.40.1.39 127.0.0.1" Would accomplish this? =G=
