RSA WTD Silvertail - varz for silvertap or other remote service won't load...remote silvertap machine(s)
RSA Silvertail is a multi-machine setup and need to view varz statistics for all components on remote systems. Varz graphs load for all local components, but the silvertap (or other separate machine) varz graphs are blank. Varz graph loads for a remote component or silvertail service, but is blank.
In /var/log/messages from the server where varzfetcher is running, you may have the following messages or something similar:
Jul 21 11:55:14 machine-name rrdcached: queue_thread_main: rrd_update_r (/var/opt/silvertail/rrd/SilverSurfer/0/--some-name--.rrd) failed with status -1. (mmaping file '/var/opt/silvertail/rrd/SilverSurfer/0/--some-name--.rrd': Invalid argument)
Varz Fetcher doesn?t use the admin user/password, it uses a different account/passwordthat is only synced to all of the nodes when you change the admin password in SilverCat.
If you?re not seeing data in Varz, then the best first option is always to go and change the admin password in SilverCat.
You can ?change? it to the same thing it?s currently set to ? it?s just the act of changing it that causes it to generate anew random password for the account it uses and re-sync it across all nodes.
NOTE: To confirm RSA Silvercat password sync is the problem, the VARZ should actually be running and created and you should be able to fetch them manually.
