Conn red and green every few minutes
by billieperez＠gmail.com 17 Mar '06

17 Mar '06

Hi, I have been running Hobbit 4.2.1 on Fedora Core 4 for several months now. Today, in the middle of a normal day when there was supposedly nothing going on that would have caused this, about 30 servers started reporting red connectivity, then a few minutes later would switch back to green, then back to red again - causing very many alerts to go out. There doesn't seem to be anything similar about the servers that this was happening to, it was just random. I was able to ping these servers from the hobbit server, so it didn't seem like there was really a connectivity issue for hobbit getting to them. I restarted the hobbit service, rebooted the server, checked the logs (nothing was logged the time it started happening). I then moved all the logs to a different directory and restarted the service. After about 1/2 hr things went back to normal. Does anyone know what might cause this strange behavior and anything to do to prevent it from happening in the future. Thanks in advance, Billie

Another RRD question
by jeffnewman75＠gmail.com 16 Mar '06

16 Mar '06

All, Somewhat similar question to one asked earlier about custom data/graphing I have a script that gets SAR data. I am creating the rrd files manually up front, as they have a different step frequency that hobbit would create. It outputs (for example) cpu0pusr:number cpu0pwio:number cpu0pidl:number cpu1pusr:number cpu1pwio:number cpu1pidl:number etc... This can vary based on the number of cpu's in the box. I am only doing this on a limited number of hosts (3) so hand creating the RRD's isn't too big of a deal. The problem is graphing. Some of these have 16 CPU's, some only 4. If I create a graph definition, it would have to be universal (i.e have up to 16 definitions for everything) but that would make the graphs for the boxes with only 4 CPU's not look right (I think, havn't tested yet) What I was wondering is, is there a way in the hobbitgraph.cfg to do something like: (NOTE: I know this syntax isn't correct, it's more for readability purposes) [sar] TITLE sar data YAXIS percent DEF:cpu$NUMpusr=sar.rrd:cpu$NUMpusr:AVERAGE DEF:cpu$NUMpwio=sar.rrd:cpu$NUMpwio:AVERAGE DEF:cpu$NUMpidl=sar.rrd:cpu$NUMpidl:AVERAGE LINE1:cpu$NUMpusr#CC3333:cpu$NUM percent usr LINE1:cpu$NUMpwio#FF0000:cpu$NUM percent wio LINE1:cpu$NUMpidl#0000FF:cpu$NUM percent idle COMMENT:\n GPRINT:cpu$NUMpusr:LAST:CPU $NUM usr \: %5.1lf%s (cur) GPRINT:cpu$NUMpusr:MAX: \: %5.1lf%s (max) GPRINT:cpu$NUMpusr:MIN: \: %5.1lf%s (min) GPRINT:cpu$NUMpusr:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:cpu$NUMpwio:LAST:CPU $NUM wio. \: %5.1lf%s (cur) GPRINT:cpu$NUMpwio:MAX: \: %5.1lf%s (max) GPRINT:cpu$NUMpwio:MIN: \: %5.1lf%s (min) GPRINT:cpu$NUMpwio:AVERAGE: \: %5.1lf%s (avg)\n GPRINT:cpu$NUMpidl:LAST:CPU $NUM idle. \: %5.1lf%s (cur) GPRINT:cpu$NUMpidl:MAX: \: %5.1lf%s (max) GPRINT:cpu$NUMpidl:MIN: \: %5.1lf%s (min) GPRINT:cpu$NUMpidl:AVERAGE: \: %5.1lf%s (avg)\n I think the more correct way is to split the RRD files into sar0.rrd, sar1.rrd, etc... and use the FPATTERN thing with the index. I can split the output up and change the test name for each cpu to sar0,sar1 etc.. so that it updates the correct RRD, but I just wanted to find out first if there is a way to do this in 1 RRD and do the work in the graph portion. Thanks, Jeff

[hobbit] CUSTOM RRD DATA VIA SCRIPTS
by greg.hubbard＠eds.com 16 Mar '06

16 Mar '06

Subhash, I think you are on the right track. But since your script needs to recognize each line and process it independently, you need to send the grep output through some sort of a loop, and then unpack each line. I am not exactly a shell wizard, but at least two approaches come to mind: A) send the output of the grep to a temporary file, then process the temporary file line by line. B) process the output of the grep line by line in a loop (skipping the temporary file). There is nothing that says that you have to process the output in shell -- you could also use Perl. Just keep in mind that you can only have one processor on your server and it has to be able to deal with everyone's needs. Or, as Henrik suggests, you can dig out a C book and write a new module to recognize all of this. I would take a swing a Perl before I would do that, since my C skills are nil. Anyone care to donate a few lines of Bourne that would help Subhash over the hump?

I thought of the following script, however I could not debug the script. I have the following questions? I thought of taking advantage of the common letters PRN and grep it with "PRN*". Is this the correct way to grep the value? Example data from server1 PRN327:0 PRN203:1 PRN202:0 Example data from server2 PRN123:3 #-----------------------name:value PRN314:0 PRN137:0 PRN136:0 The idea is to create separate rrd files of each value. The host which send the data to hobbit does not have a fixed number of name:values but maximum of 30 If I trigger the script with hobbd_rrd nothing is happening and the CPU utilisation is growing up to 90% Around 25 hosts have the test "printq" running. #!/bin/sh # Input parameters: Hostname, testname (column), and messagefile HOSTNAME="$1" TESTNAME="$2" FNAME="$3" index=0 if [ "$TESTNAME" = "printq" ] then # For test purpose looping fixed number of times. while [ $index -lt 30 ] do p[index]=`grep "^PRN*:" $FNAME | awk '{print $2}'` # The RRD dataset definitions echo "DS:$index:GAUGE:600:0:U" # The filename echo "printq.$index.rrd" #The data echo ${p[index]} let index=$index+1 #exit the loop when the value of $p{[index]} is null if [ $p{[index]} -eq "" ] then exit fi done fi exit 0 Regards Subhash -----Original Message----- From: Hubbard, Greg L [mailto:greg.hubbard at eds.com] Sent: Wednesday, March 15, 2006 9:37 PM To: hobbit at hswn.dk Subject: RE: [hobbit] CUSTOM RRD DATA VIA SCRIPTS Well, it does not appear to be that difficult. For each data element, you need to put out the DS line, then the file name, then the values. Make the file name match the element. So, if F070 = 1, F001 = 2, F037 = 5 "DS:value:GAUGE:600:0:U" "F070.rrd" "1" "DS:value:GAUGE:600:0:U" "F001.rrd" "2" "DS:value:GAUGE:600:0:U" "F037.rrd" "5" The Hobbit RRD support will do the right thing, creating these datasets in the directory for the associated host. Then, in the Hobbit graph definition, you have to figure out how to use the wildcard mechanism to find all the F*.rrd files. The file names can be used to replace the parameter value "value" in the dataset would become F070, F001, F037, etc. This seems to be how the disk magic works. Good luck!

Manipulate log rapports from a clinet

Hello Someone know but this... I have some window clients, which send messages alerts regarding entries in the log files. The question is, can i manipulate the warning level and panic level status on a clinet log file rapport at the hobbit? Just like i can change load,disk,proc,... levels in the hobbit-clients.cfg. /Bengt

hobbit client for windows..

Hi Henrik, I think we've got a nice start with Etienne Grignon's open-source windows client publish yesterday on the mailling list. What are your thoughts for the "windows hobbit-client" ? (long time ago, you talk about some development in belgium.. i think) Based on Etienne's bbwin, i sure we can have a working windows-hobbit-client in a couple days (or weeks;) I dont know if you're in touch with Etienne; Could you provide provide a guideline for the windows development ?

Quick DOWNTIME question
by allan＠zandahar.net 16 Mar '06

16 Mar '06

Hey guys I've got a memory like a rice strainer lately so please forgive me. If you define a host with a DOWNTIME flag when the host goes down during that time does it still send alerts ? I can't remember for the life of me. I know the man pages say alarms will not be triggered but I cant remember if it definately works Thanks guys Allan
