Ping Failures

If the Scan Engine is unable to ping a previously unscanned target, it will not attempt to scan it, as it regards it as being unreachable.

This may be because of a network/firewall issue, or it may be because the target is offline.

Ping failure (per project)

Given a ProjectID, to find which targets could not be scanned as they were unreachable, the following query can be used.

SELECT jobProj.ProjectID
     , ch.Target
     , ch.Label
	 , ch.DurationMilliseconds
	 , ch.Connection
	 , ch.message
	 , ch.AttemptDate
FROM history.t_CommandHistory ch 
    INNER JOIN jobs.t_JobLocationProjectIPRange AS jobProj ON jobProj.JobID = ch.JobID
WHERE ProtocolId=5 
  AND message LIKE '%Failed%' 
-- === Change this line ==== --
   AND jobProj.ProjectID = 1
-- ========================= --
ORDER BY AttemptDate DESC

Ping success

If you want to see the results of successful pings (for example to look at the round trip times) then add the word NOT in the WHERE clause

SELECT jobProj.ProjectID
     , ch.Target
     , ch.Label
     , ch.DurationMilliseconds
     , ch.Connection
     , ch.message
     , ch.AttemptDate
FROM history.t_CommandHistory ch
    INNER JOIN jobs.t_JobLocationProjectIPRange AS jobProj ON jobProj.JobID = ch.JobID
WHERE ProtocolId=5
  AND message NOT LIKE '%Failed%'
-- === Change this line ==== --
   AND jobProj.ProjectID = 1
-- ========================= --
ORDER BY AttemptDate DESC
