marking significant events on the trend charts
by tomg＠mcclatchyinteractive.com 07 Mar '07

07 Mar '07

One feature that I've always wanted and am asked for quite a bit, is the ability to add some kind of mark on the trend charts to record a significant event. For example, if my company makes a major code release and our metrics improve greatly, the ability to add some kind of line or marker to the trend chart that shows the turning point to lower CPU usage, more httpd requests, etc. Is that even an option that could be worked into Hobbit? -- Tom Georgoulias Systems Engineer McClatchy Interactive tomg at mcclatchyinteractive.com

[hobbit] NCV module for hobbitd_rrd question
by gumby3203＠gmail.com 07 Mar '07

07 Mar '07

The man page for the hobbitd_rrd program says that it "receives "status" and "data" messages from hobbitd via stdin, and updates the RRD databases used to generate trend-graphs". However, further down, it says: "The "ncv" module will automatically detect all occurrences of a "NAME : value" or "NAME = value" string in a *status* message, and generate an RRD file holding all of the name/value data found in the message" (my emphasis added). I'm trying to get some custom NCV graphs to show up in hobbit, but I only want them to show up in the "trends" column, and not have their own column displayed. Mainly, this is because I will have about 8 different graphs, and there is no need to have separate columns, since they aren't status-generating (green/yellow/red/purple/etc) columns. According to the "bb" manpage, the "data" keyword should do the job (as opposed to the "status" keyword, which I have successfully used in the past). However, the graphs aren't showing up. When I read the second quote above, it sounds like the "data" keyword doesn't pass data to the NCV module, which would explain why the graphs aren't showing up. Any ideas/suggestions?

CPU Graphs
by jkwade＠futurefrontiers.com 07 Mar '07

07 Mar '07

Hello All, I raised a question a month ago about less averaging on the CPU graph. In the hobbitclient-sunos.sh I changed the vmstat to take 15 second samples. I have another question, Does the graph view average the datapoints as well? Can I have it give me just the raw datapoints in the graph? Thanks.James

Solaris ps
by gjohnson＠trantor.org 06 Mar '07

06 Mar '07

Hey, Is there any reason NOT to use '/usr/ucb/ps auxwww' in place of the ps that hobbit-sunos.sh is using?...in other words, will it break anything if I use it (yes, I know I need to run it as root to get everything)? I prefer the output of what Henrik provides but the solaris ps is braindead (truncates at 80 characters). =G=

[hobbit] Changing the default 48h,12d,48d,576d period for graph display ?
by Thomas.Kern＠hq.doe.gov 06 Mar '07

In future releases, could this become a configuration option or must it stay hardcodes in the source code? -------------------------- Thomas Kern 301-903-2211 ----- Original Message ----- From: henrik at hswn.dk <henrik at hswn.dk> To: hobbit at hswn.dk <hobbit at hswn.dk> Sent: Tue Mar 06 10:45:59 2007 Subject: Re: [hobbit] Changing the default 48h,12d,48d,576d period for graph display ?

It isn't configurable, but in the hobbit-4.2.0/web/hobbitgraph.c file near the top of the file you'll find these lines: #define HOUR_GRAPH "e-48h" #define DAY_GRAPH "e-12d" #define WEEK_GRAPH "e-48d" #define MONTH_GRAPH "e-576d" Change them to suit you. Then search that same file for the HOUR_GRAPH etc. further down; you'll find 1 place where each is used like this: period = HOUR_GRAPH; persecs = 48*60*60; and you need to change that "persecs" calculation also for all 4 graph types. Then run "make" (from the hobbit-4.2.0 directory) and "make install" (or just copy the "web/hobbitgraph.cgi" file to your ~hobbit/server/bin/ directory).

DESCR Info in Alerts
by geoff.hallford＠gmail.com 06 Mar '07

06 Mar '07

Hi, I was wondering if there is anyway to change the default email alert contents to include the DESCR tag information for a host (without creating a custom alert script)? We have many support people who don't know what all of the hosts are for or if it goes down, what that means and I want to make it easier for them to know what is affected. Thanks.

MRTG & Hobbit
by jwood＠metrolibrary.org 05 Mar '07

05 Mar '07

I have been wrestling with this for a few days and haven't found anything pertaining to this in the archives - When I do the MRTG integration as described by Henrik, it seems to default to bits /second instead of bytes? Is there a way to change this? Also, is there anyway of showing the percentage and the units of measurement on the graph as on a standard copy of MRTG? Thanks -- John Wood IT Manager Metropolitan Library System

This gens something like: Target[sunhost_2]: 2:public at sunhost.com: . . .. Target[sunhost_3]: 3:public at sunhost.com: . . . So how do I handle two interface for hobit.

Monitoring memory on AIX
by stef.coene＠docum.org 03 Mar '07

03 Mar '07

Hi, I changed hobbitgraph.cfg so it created to extra graphs: one for Access Virtual Memory and one for the free list. See http://www.docum.org/twiki/bin/view/Hobbit/AixTips Henrik, can you add these graph definitions ? I also patched the hobbit server so it monitors the Access Virtual Memory on AIX: diff hobbit-4.2.0/hobbitd/client/aix.c hobbit-4.2.0.ori/hobbitd/client/aix.c 73c73 < long memphystotal, memphysused, memphysfree, memactused, memswaptotal, memswappct; --- > long memphystotal, memphysused, memphysfree, memswaptotal, memswappct; 80d79 < if (sscanf(freememstr, "%*d %*d %ld", &memactused) == 1) memactused /= 256; 88c87 < memphystotal, (memphystotal - memphysfree), memactused, --- > memphystotal, (memphystotal - memphysfree), -1, Henrik : The only problem is that Total for the line Actual is always the amount of Physical Memory. But this should be Physical Memory + Swap Memory. At least, this is for AIX, but I think this is for other os'es as well. I think this is a bug. The problem is that Actual can be > 100%. So, I had to change ./hobbitd/rrd/do_memory.c and remove the > 100% to get some graphs: //if ((actval >= 0) && (actval <= 100)) { if (actval >= 0 ) { sprintf(rrdfn, "memory.actual.rrd"); Stef
