--------------------------------
Summary: Add the ability to gather and expose metrics in the
gateway
Key: KNOX-643
URL: https://issues.apache.org/jira/browse/KNOX-643
Project: Apache Knox
Issue Type: New Feature
Components: Server
Affects Versions: 0.8.0
Reporter: Sumit Gupta
Assignee: Sumit Gupta
Fix For: 0.8.0
The goal would be to capture various request/response metrics in the gateway
and expose them via JMX and/or REST.
Some of the requests on the dev mailing list are:
- Capture TPS both at the service level as well as aggregate for the server
instance.
- Byte transfer counts per service and aggregate
- Unsuccessful login
- Successful login but overall return was HTTP 500 which indicates failure
on the cluster side. An example would be users connecting to Knox with
valid AD user/pass but which were not authorized in the cluster. This can
happen when the cluster is in secure mode but a service like Centrify has
not allowed the user into the cluster's zone.
- Unsuccessful AD lookup by Knox - user doesn't exist.
- Connection counts that used and didn't use an auth cookie and resulted in
an AD lookup
- Current open connections
- Capability to reset the aggregate counters while Knox is running.
- Ability to hook into Ambari's Metric collection framework.
