Nagios 3.0 and Splunk


I was just playing a test set-up for Nagios, to monitor some hosts, services and devices for me across the data center, when I ran into Splunk in a config file. Being naturally curious, I checked out Splunk...

Splunk is basically your IT search repository. It has a search engine that collects everything you want to track from all your servers. Use Splunk to collect SNMP traps, mail queues, log from web servers, firewall or routers, transaction and database logs and more. It can index anything because it uses live tracking. What it doesn't know but occurs frequently, you can teach it. Best of all, use Splunk to trigger an SNMP alert for a host or service in Nagios, when say more than 10 HTTP 404 errors occur on your corporate website. Probably there has been an error that some other system may or not have tried to inform you about... Excellent! Some assembly required of course, as everyone has different logs, needs, wishes and demands...

Oracle's Linux is RedHat and CentOS compatible. So just use those packages. It they don't work, they usually check for specific OS version strings in the script. Just modify those checks and they'll work.

Oh and the VMware image won't work. You'll need the packages or the raw sources files for Nagios. That will always work.

Preventing PuTTY timeouts

Just found a great tip to prevent timeouts of PuTTY sessions. I'm fine with timeouts by the host, but in our case the firewall kills sessions after 30 minutes of inactivity... When using PuTTY to ssh to your Linux/Unix servers, be sure to use the feature to send NULL packets to prevent a timeout. I've set it to once every 900 seconds, i.e. 15 minutes... See screenshot on the right.

Removing VGs or LVs from LVM

While are many excellent tutorials about creating and using LVM on Linux, not may show you how you can remove disks from LVM Volume Groups (VG) and reclaim storage or how to remove a Logical Volume (LV) from your LVM set-up. Here is what I did: Use -t to TEST ANY LVM action first! We are going to release 1 TB from LVM. The Volume group was extended with 1 TB storage to serve as a cheap NFS/CIFS file server when setting up our data center. It is now deprecated and replaced by a NAS so it's no longer needed. 1) check LVM; note the four 256 GB LUNs [root@server ~]# pvscan -v Wiping cache of LVM-capable devices Wiping internal VG cache Walking through all physical volumes PV /dev/sdb1 VG vgdata lvm2 [50.00 GB / 0 free] PV /dev/sdc1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sdd1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sde1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sdf1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sdg ...

Dell Linux - OMSA Hardware Monitoring

Just getting started using Dell's OpenManage Server Administrator (OMSA) on our Oracle Linux platform. There are some confusing instructions going around so it's not immediately clear what to do, hence my blogging here. :) There is a site on Dell - Hardware Monitoring , as well as a wiki with instruction on how to setup their OMSA tooling using yum or up2date. [update]My first update for their instructions: be sure your server has Internet access, as most servers will use a proxy or so. use export http_proxy=http://yourproxy.example.com:port to configure it just for the session, and setup up2date to use an HTTP proxy by editing the settings in /etc/sysconfig/rhn/up2date .
