As our networks grow in size and traffic, the capacity of our network monitoring solutions much also increase.   So how do you know when you’ll need to upgrade hardware?

The best way is to check out the vitals tab within Scrutinizer.  Scrutinizer also maintains statistics on server cpu, memory, and hard disk utilization.  Other statistics like packet loss, buffer queue and write times are very important as well.  If you’re dropping netflow packets, or ran out of hard disk space, then it’s safe to say that immediate action is required.

If upgrading the hardware is inevitable, then it is possible to migrate the existing Scrutinizer installation with minimal loss of data by following the directions below:

1. Update the existing Scrutinizer installation to the latest released version.

2. Download Full Version of the latest Scrutinizer release and install it on the new server.

3. Stop Apache, mysql, collector, filed, cron on both servers
(cron is prior to version 5.5 only)

4. backup the following directories on the new server
\ scrutinizer\html\conf.cgi
\scrutinizer\files\rrds
\scrutinizer\mysql\data\scrutinizer
\scrutinizer\mysql\data\scrutinizer_*
5. Copy the following directories from original server to new server:
\scrutinizer\html\conf.cgi
\scrutinizer\files\rrds
\scrutinizer\mysql\data\scrutinizer
\scrutinizer\mysql\data\scrutinizer_*

6. Restart the Scrutinizer services.
