FW: [hobbit] FW: RRD data points - need help with graph distortion
by Mike.Wood＠kci1.com 13 Nov '08

13 Nov '08

Hi All, I've used rrdtool resize to change the datapoints / rrd to 5760, but now some, but not all of my graphs only go back 7 weeks. For example, my 60 day, 90 day, and 1 year graphs all only go back 7 weeks, but my 2 year graph goes back to when I installed / configured hobbit originally - June / July of this year. Any idea what gives? - BTW - I have modified hobbitgraph.c to force it to show more than the 4 default graphs. Thanks in advance!

Thanks for looking! - I have a perl script to update all the rrd files: - it uses rrdtool resize <rrd file> GROW to add extra datapoints so the rrd has 5760 data points / rra (per default it has 756 data points) - it adds also MAX and MIN rra's, this is more tricky because I export the rrd to xml, change the xml info and revert back to an rrd file. Unfortunatly, I can not share this script. But with use RRDs ; use File::Find (); you can get info about the file and find them ;) Stef To unsubscribe from the hobbit list, send an e-mail to hobbit-unsubscribe at hswn.dk ***************************************************************************** "CONFIDENTIALITY NOTICE: This transmission (including any accompanying attachments) is confidential, is intended only for the individual or entity named above, and is likely to contain privileged, proprietary and confidential information that is exempt from disclosure requests under applicable law.

[hobbit] hobbitlaunch segfault / timewarp happend again
by dddugan＠iastate.edu 13 Nov '08

13 Nov '08

I recently brought up a new client that has trouble keeping accurate time...so I began encountering this time warp issue. As pointed out by Henrik in January, it is definitely an infinite loop where errprintf() calls getcurrenttime() to get its timestamp. The attached patch modifies the functions in errormsg.c to use time() instead of getcurrenttime(). That avoids any recursion-infinite loop problems, and logs or prints errors with the system's actual time instead of a Hobbit-adjusted-for-sanity time. In the absence of accurate time, I think it would be best to log in the system's time so that you can correlate Hobbit logs with other system logs. Working for me so far, but use at your own risk. Comments? Cheers.

Just comment out the errprintf-statement in lib/timefunc.c: if (timewarphappened) { /* * Tell the world about it. * Must do this AFTER changing timewarp and lastresult, * or we will start an endless loop triggering a stack * overflow because errprintf() calls getcurrenttime(). */ /* * **** prevent segfault: do not log time warp. **** * errprintf("Time warp detected: Adjusting returned clock by %d seconds\n", timewarp); */ } This is not a real solution, but it works for me. Maybe there is somebody out, who can fix this issue properly :-) Regards Alexander > Hi Henrik, > in january I reported a segfault with hobbitlaunch/timefunc.c.

[hobbit] setting up multiple servers
by bobby.lopez＠gmail.com 13 Nov '08

13 Nov '08

I guess with Hobbit 4.2.0, there is no 'etc/hobbitclient.cfg', as it has been replaced by 'hobbit-clients.cfg' ? When I configure my two Hobbit servers as discussed below, I see that there is only one server which lists the 'hobbitd' service. The other one ishows ' - '. Is this normal? Is the general idea that if both Hobbit servers are in-sync, that 'hobbitd' on a per-system basis is irrelevant, and so it only shows one?

Correct. Especially, make sure your clients are configured to send data to both servers. Regards, Henrik -- J. Bobby Lopez Web: http://jbldata.com/ Twitter: http://www.twitter.com/jbobbylopez

ping intervals

I have some servers that it is critical that I know they are down within at the most a minute to two minutes... hobbit polls every 5min if I remember right? How do I decrease the polling intervals so I can catch these connection problems quicker? Thanks in advance...

Multiple Cononsoles for Hobbit Alerts
by captkras＠gmail.com 13 Nov '08

13 Nov '08

We want to set up a master/slave hobbit server relationship, using BBRELAY, or something equivalent. Currently, we have all our alerts hitting one server, and we want those results to populate that server, and also push to a slave server. The central server where we are collecting all our status messages aren't just from a single host, but also from other Hobbit/BB servers. Essentially, we want to have a second console for the whole ball of wax, which would be on a separate (re: DMZ) subnet, with only read access to it. Can this be done? Dave -- David S.

Xymon support sites
by Galen.Johnson＠sas.com 13 Nov '08

13 Nov '08

I think we need to revisit having two (or more) separate locations for people to go to get Xymon information and monitoring tools. Having different scripts in multiple places can just confuse people. Currently, The Shire (soon to be Xymonton) is the main area for Xymon extensions. It's a wiki-based that subscribed users can add content to. When a user wishes to add a new monitor (add-on, report, etc), it provides a template to allow for consistent look and feel of those tasks. There are also plans as time permits to extend it to using one of the sqlite plugins available to enhance ease of adding/sorting new additions without having to update 2 pages. Also, those of you who have used The Shire, any feedback (both positive and negative) would be appreciated. Thoughts? =G=
