Hello – I have set up several EC2 instances and intend to give multiple users access to them via SSH. Is there any file on the server that monitors who logs in and when?

SSH logins are usually logged automatically in /var/log/auth.log. You can grep this file to check who logged in and when.

I’ve been playing around with Ganglia for the past couple of days, trying to make it to work with EC2. It was a bit of an adventure. There are two keys for running Ganglia on EC2: use unicast and set send_metadata_interval.

I haven’t implemented it yet, but I came across Facebook Scribe, and it seems like a good idea. http://developers.facebook.com/scribe/

Have a look at the free version of Splunk – it will handle the remote log file collection and also give you some really nice search and analysis tools.

Unless you are using the auto-scaling service, which has a monitoring component, there is no monitoring offered by Amazon.

Personally, I have my monitoring run on a small instance in Amazon, and then a very simple script that runs on a box in the office to monitor that one host from the outside.

This one wins.
