Radish: Redis Analysis and Monitoring Service

A hosted monitoring tool for Redis:

Radish works side-by-side with your existing Redis instances in your hosting environment. All you need to do is start a daemon which handles connecting to Redis and sending data out to Radish over HTTPS.

Using Radish, you’ll be able to:

  • analyze the amount of reads/writes
  • track information like “average commands per second, memory usage, changes since last save, and keyspace size.” (here.)
  • identify high-frequency commands and keys

Even if it looks like a very well polished product, the Hacker News community was prompt to point out that monitoring Redis using Munin or Cacti is cheaper.

MongoDB db.serverStatus() Explained: MongoDB Monitoring

The BoxedIce guys are continuing their series on Monitoring MongoDB, this time explaining parts of the db.serverStatus(): connections, index counters, background flushing (nb this is the part where MongoDB can lose your data), and opcounters.

MongoDB db.serverStatus() is similar in a way to MySQL SHOW VARIABLES LIKE 'Inno%' and SHOW ENGINE [INNODB] STATUS.

These aside, I assume this whole series is just a preamble for their upcoming MongoDB monitoring service.

Monitoring MongoDB

The guys over BoxedIce have another great article on MongoDB monitoring (and they promised a series on the subject):

There are a number of built in tools and commands which can be used to get important information from MongoDB but because it is relatively new, it can be difficult to know what you need to be doing from an operational perspective to ensure that everything runs smoothly.

I’ve mentioned in the MongoDB largest deployments post there are quite a few questions to be answered in terms of operating MongoDB and these guys seems to have gained a lot of experience with MongoDB so I hope we’ll hear more from them.

Redis Monitoring with Ganglia

Richard Crowley on how to push Redis INFO output into Ganglia:

The metrics it comes with are pretty rudimentary but they get the job done.
