How to find a proper monitoring solution Binary Talks | (1)
As in our own environment at nugg.ad every startup/HA environment needs a proper monitoring solution to fit the minimum requirements to fullfill the high availability demands of your customers. Without a proper solution you can trust on you're screwed. It's simple as that. You just need to know first whether your application servers are melting, your database/nosql backend begins to burst or someone accidentally the whole thing (you know the meme, do you?). Not only to inform customers before they call you, but also to be able to plan further growth of your environment. Since I'm currently rewriting our whole monitoring environment ...

SNMP LTM 9.x MIB Navigation Binary Talks | (0)
I recently got a F5 BigIP 3600 to put my hands on and as we all know, the MIB tree can be a bit tricky to navigate through. For the LTM 9.x release there's a really great spreadsheet available at F5's DevCentral which contains the most useful OIDs to monitor the many different aspects of the F5 BigIP series. It's even useful if you're already running LTM 10.x since the changes seems to be not that major. Small example: explanation oid (numeric) oid (alphanumeric) data type sample value global ClientPktsIn .1.3.6.1.4.1.3375.2.1.1.2.1.2.0 .iso.org.dod.internet.private.enterprises.f5.bigipTrafficMgmt.bigipSystem.sysGlobals.sysGlobalStats.sysGlobalStat.sysStatClientPktsIn.0 Counter64 220788 global ClientBytesIn .1.3.6.1.4.1.3375.2.1.1.2.1.3.0 .iso.org.dod.internet.private.enterprises.f5.bigipTrafficMgmt.bigipSystem.sysGlobals.sysGlobalStats.sysGlobalStat.sysStatClientBytesIn.0 Counter64 23139087 global ClientPktsOut .1.3.6.1.4.1.3375.2.1.1.2.1.4.0 .iso.org.dod.internet.private.enterprises.f5.bigipTrafficMgmt.bigipSystem.sysGlobals.sysGlobalStats.sysGlobalStat.sysStatClientPktsOut.0 Counter64 239780 global ClientBytesOut .1.3.6.1.4.1.3375.2.1.1.2.1.5.0 .iso.org.dod.internet.private.enterprises.f5.bigipTrafficMgmt.bigipSystem.sysGlobals.sysGlobalStats.sysGlobalStat.sysStatClientBytesOut.0 Counter64 84615725

Database fix for Nagios plugin for Cacti Binary Talks | (0)
If you're interested in running Nagios within the Cacti interface you may be interested in the Nagios plugin for Cacti (NPC) project which does a good job overall in combining these two powerful tools within the monitoring/graphing world. Nevertheless, I had a database related problem during the initial setup due to the fact that NPC brings along its own schema of the ndo database which is outdated since the last release of ndoutils 1.4b8 (they added a new column called long_output). Therefore, you want do the changes below via your mysql console to the following tables if you'd like to use ...
