What to do when an agent is offline?
When installed/restarted an agent first performs a web post to api.vistanet.jp
on port 443 to get the server to connect.
Perform the following validations if agent appears offline:
- Verify if DNS resolution is working.
- Telnet to port 443 on
api.vistanet.jp
. - In the browser, type
https://api.vistanet.jp
and verify if redirected to OpsRamp.
What if the agent cannot reach api.vistanet.jp?
If api.vistanet.jp
is not reachable, then the agent falls back to cn01-sjc.opsramp.com
after six (6) checks
to get the server URL to connect.
After getting the first response from api.vistanet.jp
,
the agent connects to the servers based on which node the client is connected to.
An agent log file appears and provides information about the agent connected to DNS.
How do I validate the agent if it appears offline?
If agent appears offline:
- Make sure DNS resolution is working.
- Telnet to port 443 on above URLs based on what URL agent is connected to.
- In the browser, type
https://Above URL/stats
. It displays a page with Agent count text. - If above validations are successful and agent is still offline, create a support ticket with the AgentLog file attached. Mention if the agent is a proxy agent or direct dgent.
What are that steps that the agent shield uses for direct agent and proxy agent?
