rrdcached results
Posted in Uncategorized on Jan 11th, 2010
My Nagios boxes run pnp4nagios+npcd to record plug-in performance data to RRD files. On one system I enabled rrdcached on, a little over 9,000 files are updated every five minutes. I saw a 30% decrease in disk write operations/second, all other things held constant. There wasn’t a noticeable difference in bytes/second, which I guess is […]
rrdcached and cacti: not quite there yet
Posted in Uncategorized on Jan 9th, 2010
I was excited to see that rrdtool 1.4 was finally released (in October), and with it rrdcached support finally in a main release. After updating rrdtool packages on a couple of my systems I sat out to make things start using the new caching daemon. Cacti was my first to play around with since it […]

Catching up

When you want to encourage search engines to index your site, don’t forget the robots.txt you wrote in 2002 that says Disallow: /. It kinda doesn’t help. Both Google and Bing have some interesting tools to help manage your search listings. Both will tell you the last time you were crawled, errors found, and other […]
I hate selinux
Posted in Uncategorized on Dec 18th, 2009
It turns out my problems with IPv6-only Net-SNMP wasn’t a problem with snmpd, it was a problem with selinux. After starting with -Dread_config -c /etc/snmp/snmpd.conf it became apparent: snmpd[9026]: registered debug token read_config, 1 snmpd[9028]: /etc/snmp/snmpd.conf: Permission denied snmpd[9028]: /etc/snmp/snmpd.conf: Permission denied snmpd[9028]: Warning: no access control information configured. It’s unlikely this agent can serve […]
Alternator replacement
Posted in Uncategorized on Dec 13th, 2009
After 170,000 miles the alternator in the truck finally decided to go south. At low (300-400) RPM after coming to a stop, the ammeter would start to droop and the engine would die. I’d have to keep my foot on the gas to keep RPM up. Otherwise while driving and idling it was fine. Fortunately […]

I finally got around to joining 2002 by using a CMS. For the past eight years I’ve been using a text editor to maintain this site. The goal is to make the content more accessible and see what happens to search engine rankings. A website with in-line images, comments, RSS feeds! It’s gonna be big! […]
