perfSONAR User Q&A and Other Discussion

[Hector Ordorica <>]

I tried to set it up on one of our perfSonar instances, but found the cacti database to be corrupt (not fully updated I believe) on a fresh install of 3.3.2. I couldn't add a router to monitor. Perhaps I misconfigured it at some point.

I eventually destroyed the database and imported cacti.sql to replace it, and added a router.

I think it's useful for monitoring the perfSonar box itself, but found the default settings for bandwidth monitoring lacking to catch the 20 second flows the throughput tests have. I tend to monitor those links with other software which polls at a much more frequent interval to get a more accurate bandwidth usage.

I don't mind it, but I probably won't be spending more time configuring it to improve it.

We'd like to know if anyone is currently actually using Cacti, which is bundled on the perfSONAR toolkit, for collection of SNMP data.

I/we don't. I feel the machine is too exposed to the public net for my taste.
If we wanted to use it, I'd set it up on a machine I have hiding behind firewalls and using other network resources to protect.

(Others, more skilled/experienced than I may be willing/able to risk this but I am erring on the side of caution and assuming that the black-hatted "them" are more wiley than I am. To this end, I try to keep our exposure to a minimum.)
