Is this logic right?

I have two machines that run redundantly. One is used more than the other, but both can perform the same function. Most of the time, I want to know when either of them are having problems. However, from 9:15 until about midnight, I have a backup job that sometimes causes I/O delays, and makes some of the tests, start flapping. So I get paged. But nothing is really wrong. So what I want is to have pages go normally at other times, but from 9:15pm until midnight, only page if both machines are red. HOST=hpna1,hpna2 COLOR=red IGNORE TIME=*:2115:2359 MAIL $NG-IM-ADMIN MAIL $NG-IM-ONCALL FORMAT=SMS REPEAT=20 RECOVERED # During Veeam's backup time, just watch the combo test HOST=HPNA COLOR=red TIME=*:2115:2359 MAIL $NG-IM-ADMIN RECOVERED REPEAT=30m DURATION>30 MAIL $NG-IM-ONCALL FORMAT=SMS REPEAT=20 RECOVERED DURATION>30 And combo is: HPNA.conn = (hpna1.conn || hpna2.conn) HPNA.hpnaproxy = (hpna1.hpnaproxy || hpna2.hpnaproxy) HPNA.http = (hpna1.http || hpna2.http) HPNA.hpnadetails = (hpna1.hpnadetails || hpna2.hpnadetails) Paul Root Lead Engineer CenturyLink Network Reliability Operations Center 600 Stinson Blvd, N.E.

rrd crashing and graph gaps on 'trends' charts with 4.3.17
by john.thurston＠alaska.gov 23 Apr '14

23 Apr '14

I'm seeing gaps in some charts and not in others. The charts for vmstat tcp ifstat show no gaps. All of the other charts show consistent gaps of several hours, followed by a brief period of data, followed by more multi-hour data gaps. After appending --debug to the rrd_data line in tasks.cfg, tailing rrd-data.log shows many messages of the form: "Peer not up, flushing message queue" and several messages of the form: "Child process 10502 died: Signal 6" This makes me think some portion of the rrd listening process is crashing, leaving gaps in my data. Can anyone suggest how to determine why the rrd is dying? Could the absence of gaps in the previously mentioned charts be because they are being populated by rrd_status rather than rrd_data? -- Do things because you should, not just because you can.

In Big Brother we tested lrpc on port 1352. This test is not working in Xymon. How can we test lrpc in Xymon?

report example
by KVerMeer＠peoplenetonline.com 22 Apr '14

22 Apr '14

I would like to create a report (if it does not already exist) that calculates red/green time for a given service for a given date range for ALL client machines configured. Or possibly a subset of clients if that is also doable. This is for an end-of-month type report. Percentages as well as total times would be great. For example. Service = conn Start = 4/1/14 00:00:00 End = 4/30/14 23:59:59 Output would be: Client1 Green: 0/0% Red: 43200/100% Client2 Green: 21600/50% Red: 21600/50% Clent3 Green: 42200/97.685% Red: 1000/2.315% .... Total Green: xxxxx/xx.xxx% Red: yyyyy/yy.yyy% Is this type of report (easily) doable? Any pointers on the best way to so such a report would be appreciated.

BB to Xymon - "[machine].net stopped reporting (PURPLE)" alerts
by earle＠isolar.DynDNS.ORG 19 Apr '14

19 Apr '14

Over the past couple of months I've been transitioning my site away from an old Big Brother installation over to Xymon 4.3.12. There's only one small problem left that I'm dealing with. At one point, I switched the BBDISPLAY server in the Big Brother "bb-hosts" file from our old (now deprecated) Big Brother server and pointed it at our new Xymon server. For awhile both kept on running and only a few machines had their Big Brother clients restarted in the interim, which caused them to start reporting in to the Xymon server instead. Our Big Brother setup used the "netstat.sh" extension to send in "netstat -i" results to BB. So these systems that got restarted began to send the same data to Xymon via their Big Brother client. Now I've completed the transition and Big Brother has been shut off everywhere. As a result for these 4 particular hosts that had BB restarted, now Xymon is complaining hourly with Subject: Xymon [NNNNNNN] [machine].net stopped reporting (PURPLE) messages containing the last "netstat -i" output it received. I thought the raw data sent from a Xymon client already included "netstat -i" output, so I thought the server would just get that info from the clients now? At any rate, some file(s) somewhere clearly has kept state thinking it should still be being sent the "netstat -i" output; how do I track down where they are so I can get these alerts to stop? Thanks, - Greg

Resending because it didn't go to the mailing list. I don't remember why it was deemed a good idea not to direct replies to the list by default. I wonder how many conversations have "gone off list" like this without the participants noticing?? Ralph Mitchell ---------- Forwarded message ---------- From: "Ralph Mitchell" <ralphmitchell at gmail.com> Date: Apr 16, 2014 7:23 AM Subject: Re: [Xymon] Subject: Re: SSL OCSP monitoring To: "Steff Watkins" <s.watkins at nhm.ac.uk> Cc: OCSP is a little different to expiry - it's for checking that the certificate has not been revoked. Say you have some kind of national ID card with certificate and key issued by a nationwide trusted entity. You could use it to access banking and health services, sign documents, encrypt email, etc. If the card is lost or stolen, you call it in, the certificate is revoked and they send you a new one. If the stolen card is subsequently used to try to gain access to your bank account, the bank calls an OCSP responder to validate the card and then rejects it. Clients, such as web browsers, can do the same to check if server certificates have been revoked before trusting them. I'm not sure what anyone would gain from testing revocation status, given that you're generally monitoring certs on your own network and servers.

> Hi, > > Can we monitor SSL certificate's revoke status ? > > Thanks, > Deepak Hello Deepak, Not sure if this is what you're after but I've found a way of getting Xymon to give yellow alerts when the SSL certificate on a webserver has 30 days (or less) until expiry, and red alerts on 14 days (or less). The first part is to give a secure URL in the comment section of the host definition in the hosts.cfg file, such as: 192.168.12.12 www # conn ssh http://www. yabadabadoo.blah.uk/ https://yabadabadoo.blah.uk/ This tells Xymon to check the secure HTTP instance on, in this case, www.yabadabadoo.blah.uk . So it picks up the SSL certificate and reports on its presence. This should create an "sslcert" column on your Xymon display. You can view the retrieved certificate in that column. However the next step is needed if you wanted alerts raised when an SSL certificate is getting near expiry date. In the tasks.cfg file you need to setup a clause to force the system to raise a warning if the SSL certificate gets near expiry date. I have done this by adding the "sslwarn" and "sslalarm" options to the definition for xymonnet. The actual definition I am using is shown below: ----- [xymonnet] ENVFILE /usr/local/hobbit/server/etc/xymonserver.cfg NEEDS xymond CMD xymonnet --no-ares --report --ping --checkresponse --sslwarn=30 --sslalarm=14 '--dnslog=/var/log/xymon/dns.log' '--concurrency=5' '--debug' '--dump=both' LOGFILE $XYMONSERVERLOGS/xymonnet.log INTERVAL 5m ----- As you can see I have '-sslwarn=30' which causes the sslcert column for a host to go yellow when the SSL certificate for that host has 30 days or less until expiry. The '--sslalarm=14' raises the alert level to red when there is 14 days or less until the SSL certificate's expiry date. I have this running in a live environment at the moment and can confirm that it does work. I'm fairly sure that you should be able to use this sort of setup for testing the revocation dates of SSL certificates for other protocols, such as secure smtp. Hope this helps.

SNAPSHOT Report and Historical Report not synched?
by David.Diep＠dc.gov 16 Apr '14

16 Apr '14

Hi everyone, When I am on 'Current Status' and select the 'cpu' report, it gives me current information, which is the output of the top command. But when I go to the Snapshot Report and go to older date and select the 'cpu' report, it returns with a date that is not that of what I selected for the Snapshot Report. Is this a bug or is it by design? Is there a way to sync the Snapshot report and the other historical reports? Thanks! David
