Monitoring Discovery Outline
3 Main Aspects
1. Per Run How did the run I scheduled go? Current/Recent Runs
2. Per Credential/Slave How well are my credentials working for me? Credential/Slave usage feedback
3. Current State What are my current access levels like? Discovery Dashboard

Discovery Run Detailed Reports
Endpoint Access Analysis Useful general starting point
Endpoint Timings Look for performance hotspots
Possible Host Devices Look for Hosts that you don’t yet
have access to
Possible Process to Port Issues Look for hosts that need
lsof/sudo to get connection mapping

Understanding Success Rate (1)
100% Success: shown in Green
Credential has been selected for Discovery All recent attempts have successfully established a session
© 2010 BMC Educational Services
Understanding Success Rate (2)
Partial Success: shown in Yellow
Credential has been selected for Discovery There were issues with some sessions
Summarised by type of issue

Understanding Success Rate (3)
Never Used: shown in Blue
Credential has never selected for Discovery

Understanding Success Rate (4)
100% Failure: shown in Red
Credential has been used All attempts have failed
Summarised by type of issue
If the credential has worked in the recent past this will also be indicated This may mean that there has been a recent access change that should
be investigated

What Is Counted As a Failure?
Any failure to establish a Unix or Windows session
Where a session is established but HostInfo or InterfaceList methods do not complete This will prevent a Host node being updated DeviceInfo will already exist as we have a session
Where a session is established with a credential marked as “Become Super User” fails to SU This will be reported as a success and a failure

Reports are also available under the Discovery tab Discovery Reports

Current UNIX and Windows Access
Check to see that the access methods and Windows slaves you expect are in use
Check in Probe sector for access regressions or Hosts without credentials rolled out

Discovery Radar
Classifies the last access to IPs that Discovery thinks are hosts
