[hobbit] SMTP and FTP Services Red
by PNIXON＠ci.somerville.ma.us 02 Dec '06

Did you try putting an entry for Hobbit server into their hosts files? I think the delay is from the Server trying to do a reverse lookup on the IP Address. You may also have to change the order in which they resolve DNS.... in /etc/nsswitch.conf (or whatever is appropriate for your distribution) change from hosts: db files nisplus nis dns to hosts: files nisplus nis dns db _____ From: Geoff Hallford [mailto:geoff.hallford at gmail.com] Sent: Wednesday, November 29, 2006 3:46 PM To: hobbit at hswn.dk Subject: [hobbit] SMTP and FTP Services Red Hello, On a few of our servers the SMTP and FTP services are RED but when I telnet to them, they do show the proper 220 status good. They are quite slow to respond though, taking sometimes 10-15 seconds. Is there anyway to get Hobbit to pause and wait for this? If not, how long does it wait before it shows a red status? Thank you very much for your help. Geoff Hallford

Hobbit-alert depends?
by dan.mcdonald＠austinenergy.com 01 Dec '06

01 Dec '06

Currently there is a depends construct in bb-hosts with a fair number of limitations. I would like to set up some dependencies in the alerts section instead. For example, I monitor ups's for estimated runtime and actual time on battery. I currently alert whenever a UPS goes on battery, and when runtime is less than 30 minutes. I would like to alert on runtime only when we are on battery. -- Daniel J McDonald, CCIE # 2495, CISSP # 78281, CNX Austin Energy http://www.austinenergy.com

lsof monitor?
by jkwade＠futurefrontiers.com 01 Dec '06

Has anyone written or will Hobbit monitor the number of open connections to an application? As an example, using lsof. Sorry if I'm repeating myself. I asked earlier but didn't get an answer. I thought I'd ask again and see if anyone knows a way to monitor it across the clients. I want to check and alert if an application has to many open connections. ie. >1000 Thanks..James

What does "HTTP error 0" signify when given as the result of an http test? An empty page? Thanks, Larry Barber

resolver failures
by dan.mcdonald＠austinenergy.com 30 Nov '06

30 Nov '06

I am seeing intermittent resolver failures in /var/log/hobbit/bb-network.log. This box also runs MRTG, which chews up a lot of resources with as many points as I monitor. The failures appear to occur one minute and 3-10 seconds into the MRTG polling cycle, during which time the box is CPU bound for about 30 seconds (decrypting several thousand SNMP V3 PDU's) Is there a way to extend the ares resolver timeout? Or is there some local resolver caching I could set up to help mitigate this problem? At any other point in the MRTG polling cycle the resolver seems to work fine. The other pieces cause the system to be network bound during the initial poll (about 25 seconds), and disk bound (40 seconds) whilst re-writing the ~6000 RRD files. -- Daniel J McDonald, CCIE # 2495, CISSP # 78281, CNX Austin Energy http://www.austinenergy.com

Client data not appearing on hobbit server
by Allan.Marillier＠dana.com 30 Nov '06

30 Nov '06

I know I've had this problem once before but I don't remember how I resolved it, and have not yet been able to find an answer while searching the archives. Any clues, please help! I have a server running hobbit-4.1.2p1 on Fedora Core 4, and a new one I am migrating to which is running hobbit-4.2.0 on Fedora Core 6. On the older 4.1.2p1 server I have many client servers correctly reporting their data (CPU, memory, filesystems etc.) and a few that are not. Only the conn, ssh, ftp, html etc tests initiated by the server are displaying data. My entry in bb-hosts is exactly the same as for some other servers where data is being correctly reported and all hobbit client processes look normal with nothing unusual in log files. In troubleshooting today I also compiled and started the 4.1.2p1 client on an HP-UX server and verified all configs there look good. I also have some servers configured on the 4.2.0 server running the client installed from the pre-built FC5-hobbit-client-4.2.0-1.i386.rpm that are not reporting in any of the data. Both servers have plenty of available disk and seem to be functioning normally. The hobbit server IP address is correctly configured in BBDISP in hobbitclient.cfg on the 4.1.2p1 client, and in HOBBITSERVERS in /etc/default/hobbit-client. In both cases, I can telnet to port 1984 of the hobbit servers from the clients The hobbit processes are running correctly: hobbit 21472 1 0 Nov23 ? 00:00:00 /usr/lib/hobbit/client/bin/hobbitlaunch --config=/usr/lib/hobbit/client/etc/clientlaunch.cfg --log=/usr/lib/hobbit/client/logs/clientlaunch.log --pidfile=/usr/lib/hobbit/client/logs/clientlaunch.plmws01.pid hobbit 7855 1 0 09:44 ? 00:00:00 sh -c vmstat 300 2 1>/usr/lib/hobbit/client/tmp/hobbit_vmstat.plmws01.7838 2>&1; mv /usr/lib/hobbit/client/tmp/hobbit_vmstat.plmws01.7838 /usr/lib/hobbit/client/tmp/hobbit_vmstat.plmws01 hobbit 7857 7855 0 09:44 ? 00:00:00 vmstat 300 2 Log files look normal: -rw-rw-r-- 1 hobbit hobbit 452 Nov 25 11:32 clientlaunch.log -rw-rw-r-- 1 hobbit hobbit 6 Nov 23 21:55 clientlaunch.plmws01.pid -rw-rw-r-- 1 hobbit hobbit 0 Nov 23 21:55 hobbitclient.log cat clientlaunch.log: 2006-11-29 09:54:17 hobbitlaunch starting 2006-11-29 09:54:17 Loading tasklist configuration from /usr/lib/hobbit/client/etc/clientlaunch.cfg Thanks! </PRE> <div style="font-family:arial;font-size:8pt;"> <hr> <p>This e-mail, and any attachments, is intended solely for use by the addressee(s) named above.

Hobbit help
by vorpini＠gmail.com 30 Nov '06

30 Nov '06

Dear Mr.Storner, my name's Giorgio Volpini, I'm a Computer Science student of the university of Pisa. I need some help about your program : Hobbit. Few months ago I used Hobbit during my stage and now I'm writing a thesis about it. I'd like to complete my report with a dimostration of Bash-script to use in the program; my problem is that i don't know Bash-scripting and I have not enought time to learn it. If I don't give you too much trouble, I needa script to control the time of presence rivelators connected in Lan with Hobbit server. I also have a general idea about the script: - ping the rivelator - compare the time of the answer packet with Hobbit system time - decide if it's all ready or not - warn the administrator with e-mail, sms or only with Hobbit web interface I need only a dimostrative script to add an my report, so is not important that it works perfectly, but only that bash-script has right syntax. Your help is very important for me and I think it is an work for you. Thank you very much for your attention. Your faithfully. Giorgio Volpini.

ncv problem
by stef.coene＠docum.org 30 Nov '06

30 Nov '06

Hi, I'm running hobbit 4.1.2p1 on AIX. I want to use ncv for graphing. My self-written test returns a html table. To get this displayed correctly, I send something like this to the hobbit server: ----- </pre> <table> blabla </table> <pre> ------ This is working fine. But adding ncv to the mix is causing problems. Adding the ncv info before </pre> has the result that I have a graph, but the rest is cut off. Adding ncv after <pre> means no graph and the rrd file is filled with 3 counters. It looks like hobbit is parsing the <table> and some <tr> lines as counters. Is it possible that the ncv modules dislikes html code in the message ? Stef
