Henrik, Can you say if / when the ability to change the "disk status based on free KB" feature will be included in Hobbit?

Monitoring RAID status
by Thorsten.Erdmann＠daimlerchrysler.com 30 May '06

30 May '06

Hi, I once extended the BigBrothers Disk Script to show a status dot and the sync status of mirrored disks in front of every filesystems status line. Now I migrated to Hobbit. Nearly all works fine but this extension causes the disk graphs to fail. If I understand it right, the do_disk.c program simply reads each line of the status file and displays the fifth column as the disk usage. Since my outfile from the client has two columns in front of each line this fails. The disk usage is now on column seven. I can now alter the C code but that's bad if I ever install a new version of Hobbit. So is there any idea out there how to add data to an output file without disturbing the Hobbit's standard functions. BTW: the disk test on a RedHat Box shows one "graph" to much. It's only a non referenced link, so I think Hobbit tries to interpret things that it cannot read, maybe the title line of the DF commmand's output. Thanks for help Thorsten Erdmann

include directives in hobbitlaunch.cfg, hobbitgraph.cfg
by bgmilne＠staff.telkomsa.net 30 May '06

30 May '06

Since we're looking to package some of our (server and client) extension scripts for hobbits in RPMs (to work nicely with the rest of our server deployment setup for Linux boxen), it would be really convenient if we could dump the entry for hobbitlaunch.cfg/clientlaunch.cfg and hobbitgraph.cfg in separate files, and use include directives (with support for globs) in the relevant config files. ie, supporting something like: include /etc/hobbit/hobbitlaunch.d/*.cfg Regards, Buchan -- Buchan Milne ISP Systems Specialist B.Eng,RHCE(803004789010797),LPIC-2(LPI000074592)

two questions on content test

Hi, it's possible to make, for the same host, more content check and put the result under the same column? Henrik have you in plan to add the possibility to hide the tested URL and content output? regards, Marco

Hobbit client data truncated by server?!
by saam＠tomikoni.de 30 May '06

30 May '06

Hi, after reading the docs, searching the list, searching the source code i have no idea, what is going wrong here: Data that is sent by the hobbit client is truncated somewhere. My Hobbit client messages are about 30kB. The client sents the message to the server without loss (verified with netcat). Monitoring the client channel via [clientlogger] CMD hobbitd_channel --channel=client cat in hobbitlaunch.cfg results in: > >DATADATADATA >DATADATADATA >DATADATAD > >... DATA TRUNCATED ... > The received data is cut at approx 10kB. All MSG_* variables that limit communication are clearly above this value (MSG_CLIENT=256*1024). I have set anything to debug with no results. I did not find the place in the source code where the "DATA TRUNCATED" message is generated, so i can't trace back why it is truncated... Help me please! Regards, Mirko ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

RECOVERED alerts still sent outside of TIME window
by EES2Y＠hscmail.mcc.virginia.edu 29 May '06

29 May '06

Howdy all, We just had one of our engineers get a rude awakening last night by a UPS that had recovered from an error; I had thought that the RECOVERED pages were under the same TIME restrictions as normal alerts, but a quick look at the code leads me to believe that this is not so. Before I (or somebody else ;) attempts a fix, I wanted to make sure that there wasn't a valid reason behind this implementation. (I'm looking at the criteria match routine in the do_alerts.c file, specifically lines 899 through 914). TIA, -Eric Schwimmer Network Engineer UVA HSCS Network Engineering

OpenLDAP performance and replication monitoring with Hobbit
by bgmilne＠staff.telkomsa.net 09 May '06

09 May '06

We run a number of OpenLDAP servers, currently we have about 11 in production (depending how you count clusters) and a few in DR sites etc. We have been doing performance monitoring in the past (ie running scripts via snmp, monitoring with mrtg), but it seemed logical to move it to Hobbit and do everything in one place (useful for the syncrepl monitoring below). We have two separate instances that we manage, only one currently uses Hobbit for production monitoring (the other installation has hobbit installed, which is publicly accessible at present, but isn't used for production monitoring). The instance with the publicly accessible installation has OpenLDAP 2.1 and 2.2 servers, the other one has OpenLDAP 2.3 servers (using sync replication). So, I have written an extension script using perl-ldap (and Date::Manip) which we are now using via Hobbit's ncv module for performance monitoring. Replication status of sync-repl slaves is also checked (green for in sync, yellow for out of sync, clear if the sync-repl master could not be contacted to check the contextCSN, green if it is not a sync-repl slave). The script is available here: http://www.zarb.org/~bgmilne/bb-openldap.pl An extract from hobbitgraph.cfg is available here: http://www.zarb.org/~bgmilne/hobbitgraph-ol.cfg Some examples: http://196.25.211.20/hobbit/ldap/ldap.html Slave running OpenLDAP 2.2.x: http://196.25.211.20/hobbit-cgi/bb-hostsvc.sh?HOSTSVC=io.ol Master cluster running OpenLDAP 2.1.x: http://196.25.211.20/hobbit-cgi/bb-hostsvc.sh?HOSTSVC=metis.ol The only problem is with the parsing in ncv when a slave is out of sync. For slaves using sync-repl (no examples publicly available for now), the "&green Not a syncrepl slave" can be something like: &yellow dc=mydomain,dc=com out of sync 4 weeks 4 days 15:5:11 behind or &green dc=mydomain,dc=com in sync (with one such line for each syncrepl database, we have two or more on our production OL 2.3 boxen) Now, I could s/:/;/g or similar, but it would be nice if there were a way to prevent ncv from parsing a line (since I would also like to be able to graph the CIM extension results with ncv, but it has output and &green/&yellow/&red's all over).

hobbitclient on solaris: using iostat for cpu stat
by grossi＠acantho.net 09 May '06

09 May '06

Hi Henrik, I have seen that hobbit clients collects cpu stats via vmstat, now i think that the cpu information provided by "iostat -c" is more accurate, because it has the "%waiting for i/o" columns, wich is also in the linux version of vmstat. do you think you can add this information? -- Gianluca
