Description Anand Paladugu 2018-06-26 00:30:14 UTC
Description of problem: Ping Latency metric in Cluster view / Performance section requires clarification.  The latency to gluster nodes is from the host where WA is deployed. It's possible that WA is actually deployed on one of the gluster nodes, but this needs to be clarified in the information text for the panel. With out this info customer would not know how the latency is measured.


Version-Release number of selected component (if applicable): 3.4 (Sandbox environment)


How reproducible:


Steps to Reproduce:
1. View Ping Latency panel in the performance section in Cluster view dashboard.
2.
3.

Ping Latency chart

Comment 5 Nishanth Thomas 2018-06-28 04:51:13 UTC
This is the ping latency from server to the storage nodes. Information text needs to be updated to reflect the same

@ju - can you help by providing the correct tool-tip?
current tool-tip: "The Ping Latency panel displays the ping latency for each host in a given cluster."

Comment 7 Ju Lim 2018-07-02 20:55:30 UTC
How about "The Ping Latency panel displays the ping latency from the tendrl server to each host in a given cluster being monitored, i.e. this provides insights into the quality of your network connection between the monitoring tendrl server and the tendrl nodes.

If tendrl naming is not shown downstream, please replace with the RHGS WA moniker.

Comment 8 Ju Lim 2018-07-03 13:22:02 UTC
Updating text to be more generic i.e. doesn't include word tendrl or WA server:

The Ping Latency panel displays the ping latency from the management server to each host in a given cluster being monitored.  This provides insights into the quality of your network connection between the management server and the hosts being monitored.

The text in Ping Latency tool-tip was updated accordingly to comment 8 (attachment 1464907 [details]).
