Job Serving Diagnostics

Server Configuration

Servers should be activated, running, configured for queue processing and have non zero values for MaxQueueLength and MaxActiveJobs.

    select ServerID, convert(nvarchar(50), Hostname) as Hostname, ss.Name as ServerState, MaxQueueLength, MaxActiveJobs, IsQueueProcessingEnabled 
      from config.t_Server s
     inner join config.t_ServerState ss on s.StateID = ss.ServerStateID

.

Location Configuration

Each location must be enabled and linked to to a scanning server. The MaxScanningCount dictates how many targets in the location can be scanned at one time.

select l.Name as Location, l.IsEnabled, l.MaxScanningCount,
       s.ServerId, s.Version, s.Hostname
  from config.t_Location l
  left join config.t__Location_Server ls on l.LocationId = ls.LocationID
  left join config.t_Server s on ls.ServerID = s.ServerID
  left join config.t_ServerState ss on s.StateID = ss.ServerStateID

If there is a scan window for the location, jobs will only be served during this time. If the scan window is an exclusion, there needs to be a non-exclusion scan window for jobs to be served.

select sw.*, swwd.WeeklyDays, l.LocationId, l.Name
  from config.t_ScanWindow sw
  left join config.t_ScanWindowWeeklyDays swwd on sw.ScanWindowID = swwd.ScanWindowID
  left join config.t_Location l on sw.LocationID = l.LocationID

.

Project Configuration

The project should be running...

select p.Name as Project, ps.Name as [Status]
  from config.t_Project p 
 inner join config.t_ProjectState ps on p.ProjectStateID = ps.ProjectStateID

.

Current Snapshot of Incomplete Jobs

    select s.ServerID,  convert(nvarchar(50), s.Hostname) as Hostname, tp.Name as JobPhase, ts.Name as JobStatus, j.JobId, ParentJobID, convert(nvarchar(50), j.Hostname) as Hostname, j.IPAddressBinary, IsComplete, StartDate, EndDate, DATEDIFF(hh, StartDate, getDate()) as 'Duration {Hours)',   q.JobStatusID, 
           '            QUEUE DATA  -->          ', js.name as QueueStatus, DisabledUntil, [Priority], Source, QueueId, IgnoreConfiguredIPs
      from jobs.t_Job j
     inner join config.t_Server s on j.ServerID = s.ServerID
     inner join jobs.t_TargetStatus ts on j.TargetStatusID= ts.TargetStatusID
     inner join jobs.t_TargetPhase tp on ts.TargetPhaseID = tp.TargetPhaseID
     inner join jobs.t_Queue q on j.JobId = q.JobID
     inner join jobs.t_JobStatus js on q.JobStatusID = js.JobStatusID
     where tp.TargetPhaseID = @PHASE_IN_PROGRESS
        or IsComplete = 0

Confirm Job Serving Threads are Running

1. Open SQL Profiler
2. Select the File > New Trace menu option and login to the server.  There are some specific permissions/securables (ALTER TRACE maybe). A sys admin user will definitely have access.
3. In the Trace Properties dialog which appears, select the Events Selection tab.
4. Click the Show all events and Show all columns checkboxes.
5. In the event list, ensure only the following items are ticked..
   • Stored Prodedures
     • RPC: Completed 
     • RPC: Starting
     • SP: Completed
     • SP: Starting
6. Click the Column Filters button.
7. Add Like filters for the following properties (if there is a pre-existing filter on ApplicationName, leave it there)…
8. DatabaseName:   Name of iQSonar database. (Normally iQSonarSE)
9. HostName: Hostname of the scanning server
10. TextData: %jobs%
11. Start the trace

Let it run for about 5 minutes. You should see repeated entries for jobs.QueueStep2_SetJobStatus and jobs.Targets_Serve. If you don't see this, it's likely the threads have fallen over and a service re-start may be required.

What about the logs?

Search the Service logs for the text iQSonar Job Poll. How much information you see here will depend on the level of logging (configuration for this not in scope here). Look for errors or warnings - but also look for messages similar to any of the following...

• No queue capacity.
• Queue processing is suspended
• Polled N new targets
• No new targets available
• Failed to process target
• Job acquisition stopped
• iQSonar license has expired - scanning is suspended
• iQSonar Server not activated - scanning is suspended.
