comment does adding heaps of drives to a raid 0 increase performance?
With rotational media, isn't there also an issue of seek time vs transfer time? Adding more disk spreads the amount being read/written across more platters (each has to do less == faster) but they all still have to perform a seek operation (not reduced by adding more drives). So, depending on the type of operations you're performing (ie. lost of small reads vs a few large reads), increasing the transfer speed (by adding more drives) could make a small or large difference.

comment is a CNAME to CNAME chain allowed
Although I do this all the time, the quote above is out of context. Just above this paragraph it reads.. Domain names in RRs which point at another name should always point at the primary name and not the alias. This avoids extra indirections in accessing information.

comment Troubleshooting Nagios alerts; aka. Why aren't my alerts firing?
Had the first two but I'd somehow missed debug_level. debug_verbosity=2 also helped. These tips gave me the insight I needed to troubleshoot the (many!) other issues I hit before finally getting it working. For that, you get the Big Green Tick.

Permissions did end up being one of the issues. I've also hardcoded the path but didn't test if it specifically made a difference. Cheers
