Fwd: About CPU load (OPEN)
by oyvind.bjorge＠telenor.com 08 Apr '13

To be able to estimate this it is good to understand what this load value is showing. There is plenty of people that has explained this in a better way than I’m able to (This is one example: http://en.wikipedia.org/wiki/Load_(computing)) but still I will give you my very simplified understanding. The load is number of tasks in the runque. In my head, to utilize your resources perfectly, the value 1 for single CPU would be good, since than there should be minimal delay, but still there is always something to do for the CPU. If the value are > 1 for a single cpu, than there will be wait time for tasks to be done. This is not necessary an issue, depending on what the machine is used for, and the world is not perfect, so this will not always be the same. Therefor it also is an average value we are monitoring. A long que for a short time is normal and the reason we have ques. Problem is if the que over time is longer than the cpu can process giving delay and degraded performance. Again, what is acceptable for one machine is depending on the tasks it shall do.

I think no, just set it too low (I use the default value to start generally) and wait for it to get annoying and raise it accordingly.

El 07/04/13 18:16, Novosielski, Ryan escribió: This default is a reasonably nice default for a single CPU system, but this is really a parameter that is site-dependent. For example, I have a 24 CPU compute server. A load of 5 is hardly breaking a sweat. In some cases, high load doesn't even affect the system and you wouldn't want to be notified until a normally unreasonably high value. I'd suspect 10.0 15.0 for your system or 15.0 20.0 might not be a bad guess.

Hi. Does anyone have an experience with using xymon to monitor remote sites? How do you handle the security side of things? Can we use xymon with SSL for example? Thank you. Jon B.

proc tracking graph not working.
by Paul.Root＠CenturyLink.com 04 Apr '13

Hi, So I have the following in my analisys.cfg (4.3.10): HOST=iadccmp1,iadccmp2,apaccmp1,apaccmp2 FILE /usr/local/dat/naIpAddrs.txt yellow MTIME<3630 PROC sshd 1 300 yellow PROC sshd 1 1000 red "TEXT=ssh daemon (sshd)" "TRACK=ssh daemon" HOST=* EXHOST=iadccmp1,iadccmp2,apaccmp1,apaccmp2 PROC sshd 1 70 yellow PROC sshd 1 100 red "TEXT=ssh daemon (sshd)" But I'm still not getting the graph tracking the number of connections. Any ideas? Paul.

--debug not working for xymonlaunch?
by David.Mills＠ngc.com 04 Apr '13

Hello, All... We have a nasty problem ongoing flapping problem with our network-based tests (e.g. HTTP/SSH/DNS/etc. - see http://lists.xymon.com/archive/2013-March/037071.html) and last night I tried to use the "--debug" flag on "xymonlaunch". Unfortunately, nothing got sent to any files and nothing extra happened on STDOUT. What did I do wrong? Xymon 4.3.3 - Updated "xymon.sh" like this: ... /export/xymon-4.3.3/server/bin/xymonlaunch \ --config=/export/xymon-4.3.3/server/etc/tasks.cfg \ --env=/export/xymon-4.3.3/server/etc/xymonserver.cfg --log=/var/log/xymon-4.3.3/xymonlaunch.log \ --pidfile=/var/log/xymon-4.3.3/xymonlaunch.pid \ --debug=/var/log/Xymon/xymonlaunch-debug.log # This last switch was the addition echo "Xymon started" ~~~ Did a "xymon.sh restart" (several times) and no log file. Then I tried removing the "=....log" , with just the "... --debug" and stopped/restarted things. All with no success. Any ideas? Thanks! david ~~~~~~~~~~~~~~~~~~~ David Mills Systems Administrator Northrop Grumman 512-595-1238 david.mills at ngc.com

Custom graphs, non-standard config
by haertig＠avaya.com 04 Apr '13

04 Apr '13

My installation is an old Hobbit 4.2.0 one, but in case the graphing is still similar to the way Xymon does things nowadays, I thought I'd ask here. I am familiar with custom graphs, using NCV, and have implemented many. I am looking to try something a little different from that. I have a network appliance (not a "server") that cannot have the Hobbit client installed on it, but I can gather CPU load info from it like this "ssh user at appliance status cpu". This generates a response like this example: 0.18 0.14 0.10 3/74 29150 Command Result : 0 (Success) I currently use the above collected data to create a "status" message that I then use the "bb" command to send to Hobbit. Works as expected, with the data showing up in the "cpu" column for this appliance I am monitoring: /usr/local/bin/bb 192.168.0.1 status qcosvhsm1.cpu green Tue Apr 2 15:55:16 2013 CPU load ======== &green 5 minute average CPU load is 0.10, which is <= warning level of 3 load average: 0.10, 0.10, 0.09 Raw data (command = 'status cpu'): 0.10 0.10 0.09 3/74 7177 Command Result : 0 (Success) (I have other custom stuff that turns text like "&green" into a link to the green light icon Hobbit normally uses, but that's irrelevant to my questions here.) What I would like to do is use the built-in RRD and "CPU Load" graph definitions to display a graph on the Hobbit webpage. I realize I can make my own custom ones, and I know how to do that already (but not showing up on the default "cpu" column, I'd have to make a different "cpu_load" column using a different name than just "cpu"), but I wanted to try sending my data into Hobbit to force it to use the built-in definitions rather than my own custom defs. You can see in the above bb message I formatted a part of the text as "load average: 0.10, 0.10, 0.09" so that would mimic what Hobbit normally sees in the data typically collected with "top" (which I believe is how it collects data on CPU load - but I'm not sure of Hobbits internals in this case - possibly it uses some other command, maybe "uptime"). Do I need to send an additional "data" message along with the "status" message above to trigger the graphing? What format would that data message require? Typically for a custom graph you add onto the TEST2RRD line with "column_name=ncv" but I can see as part of the original TEST2RRD line that there already is a part that says "cpu=la". As I understand TEST2RRD (and I don't understand it all that well), I think this means that incoming "status" and "data" messages for "cpu" are directed to some internal "la" module. I am working on the assumption that all's I need to do to invoke the built-in graphing defs for "CPU Load" is to format my custom status message so that the "la" module can parse out the load data it needs for graphing. Am I even close to being correct in this assumption? Any tips on how I should proceed? This is as much a mental gymnastics exercise as anything. It is going into a production system and I know how to skin this cat another way. I was just hoping to learn how to skin this cat using the already built-in "CPU Load" graphing definitions. Thanks in advance!

xymond_alert --test feature request
by Phil.Crooker＠orix.com.au 03 Apr '13

03 Apr '13

When using this facility, I've found it will show an alert for a service that is not being monitored. For example: host.cfg entry: 10.1.2.3 whatever.au # http smtp NAME:"Sample Entry" alert.cfg entry: HOST=whatever.au MAIL someone at whatever.au COLOR=RED So, if I do this test: xymoncmd xymond_alert --test vho64pl09.orix.com.au blah it will return an alert. I understand that the alert.cfg just says to alarm on any RED condition, but it would be useful for this test to actually check that the service is in fact one being tested for. This already tests that the host has a hosts.cfg entry (very useful when working from a separate host list), it would be nice to extend this to the actual test as well - a single cross check on the whole chain of config files to ensure alerts are working as expected. thanks, Phil
