Monitoring and measurement software, the search
Oct 11th
While at VMworld 2011, I spent a lot of time at the expo (where companies were peddling their wares) looking for 2 items.
- Storage vendors who do things via NFS.
- Monitoring and measurement companies to help me consolidate the multiple pieces of software we run today.
This post is about #2.
I looked at a ton of software while at VMworld and more once I got back and I had fallen in love with LogicMonitor, found via a google search.
I also looked at a bunch of things once I got back, but LogicMonitor still keeps on winning on everything technical for us.
Understands things like VMware (vCenter and ESXi via SDK), SNMP devices (including device specific items like F5 extensions, Fortigate), measurement of data from Apache, MySQL (and I assume other databases), etc.
I’ll write more later, need to finish up my slightly extended beta test and work on the alerting function.
Check them out, so far so good.
MySQL, data partitioning, and me
Jan 26th
So I have this database of bytes transferred from many of the devices on our network.
It queries these devices every 5 minutes storing many pieces of data, from the number of packets in and out to the number of bytes (or octets in network speak) in and out on an interface. (it also gathers statistics on errors, Cisco environment items, discards, etc). I am mostly concerned with the bytes transferred, so while the other data is collected – I am not using it at this point.
But what happens when you have 16 months worth of data?
Before you say ‘i dunno’, I’ll tell you: it is slow to query it back out, even with minimal indexes.
I have ~54 GB of data (including indexes), and 250 tables (each device has multiple tables, each table stores one type of data only).
So, how to get some speed back? Read on!
FreeBSD 7 does feel faster!
Sep 4th
This past couple of days, I worked with our web guy as I redeployed our web cluster from FreeBSD 6.x-STABLE to FreeBSD 7.x-STABLE.
We also moved from the rock solid and never failing (and now end of lifed) PHP4 to PHP5 along the way.
My subjective view of FreeBSD 7 vs 6 on our web cluster gives me the feeling that 7 does feel faster with the new ULE scheduler.
I say subjective because I didn’t take real benchmarks before or afterwards, only on how the system felt (responsiveness) and using very basic tools (top, systat -vmstat).
