I think I speak on behalf of Volker and Stefan, when I say that we have little hope that IBM/Lotus will ever fix what they buggered up. I for one, don't want to keep checking.
While waiting for a phone call, I whipped up a little Nagios / Icinga plugin to monitor the "progress" of the [...]
There's no doubt that e-mail is a vital component in business today, and as such we pay particular attention to our e-mail infrastructure.
We use dedicated systems as Mail Transfer Agents, of course, and run Exim on those, with as little ballast as possible. What we do though, is to give each MTA its own DNS [...]
heise Netze has an updated article (in German) on how to monitor your own server's existance on a DNS black-list (DNSBL) with Nagios. (Icinga will work just as well, of course.)
The script is simple enough, and should pose no problem getting that into Nagios. It is also very easy to add or remove DNS [...]
One of our Web servers was rendered almost useless for clients because the Certificate Revocation List we have on it, expired. To avoid that happening again, I decided to implement a check for the CRL expiry as a Nagios (respectively Icinga) plugin.
I grabbed the OpenSSL source code, and in the apps/ directory, I used the [...]
I was warned a few minutes ago by my favorite monitoring software that something was amiss: a vital system's disk was running full.
Sixty odd days of antivirus signature files are just a bit too much volume for the disk:
# cd /usr/local/uvscan/datfiles
# df -h .
/dev/sda3 [...]
Icinga, the new fork of the Nagios network and system monitoring platform, has been released to the public:
The Web interface looks very snazzy, and it is pretty snappy. Check out the demo site (user: guest, password: guest).
I read Learning Nagios 3.0 by Wojciech Kocjan, in spite of knowing a bit about Nagios.
The book's subtitle is A detailed tutorial, and it is all of that. The eleven chapters of Learning Nagios 3.0 contain just about all I'd want to know about Nagios.
The book starts off by explaining what system and network monitoring [...]
Nagios (or its recent fork Icinga) implement an Open Source network and application monitoring system. I use Nagios extensively, and I wanted to build an Arduino monitor for it — a little gadget that sits next to my screen, where I can glance at it quickly to see if everything is running.
As you'll see below, [...]
