I noticed an intermittent slow response on the ping from my application server to my database server. So to diagnose, I tested using a standard ping and Telnet tests.
For the telnet tests, it was able to connect. However some telnet took longer to connect than others.
For the ping, I noticed that I am missing a lot of icmp_seq. It was skipping occasionally. On the other server, it was communicating very sequentially.
But for the app to web and app to app, there were no skipped items. From the app to DB there is.
Anyone have any idea on what is happening ?
Just to add, the database response was very intermittent as well. Sometimes slow. The application server and database are on different network segments as well.
What can we look at ?
