Abstract
ITNM 4.2 using SysLocation for ncp_gis geographical discovery
Body
This blog entry will look at basic configuration and simple troubleshooting for the most common way to configure the geographical discovery. Using location records from device data.
Quick link to device record geographical location discovery
First let's start at the end. Whether I've used device data, or a csv file discovery of location information how can I tell if it made it through the discovery?
https://eforce.server.com:16311/ibm/console/nm_rest/topology/locations
{"locations":[],"instrumentation":{"count":0,"processTime":0,"totalExecTime":0,"queryTime":0}}
I call this the 'rest test'. If this comes back at '0' like above and you believe that correct location discovery data exists something has gone wrong. So now let's move back to the beginning of the device discovery information.
From the doc link above, is the this statement true?
geographical data was added to the device record in the SysLocation field in the following format: location address;longitude;latitude.
Let's troubleshoot this in my lab
First according to the documentation above is the stitcher ready to use?
-bash-4.2$ pwd
/opt/IBM/netcool/core/precision/disco/stitchers
-bash-4.2$ tail PostLayerProcessing.stch
}
ExecuteStitcher('AddClass' );
ExecuteStitcher('AddChassisIPTag' );
// Sample stitcher to enrich geographic location based on the
// syslocation of a device being is specific parsable format
ExecuteStitcher('AddGeoLocationData');
}
}
-bash-4.2$
Sure the 'AddGeoLocationData' stitcher has been uncommented out.
Next
-bash-4.2$ ./ncp_oql -username admin -domain ECOMS -service disco -latency 222222

The first entry of the two looks good, but look at the second. The SysLocation field is missing longitude and latitude. This one will not pass through the discovery.
You can skip to the final table in -service disco to see how this stitcher processed these fields.
|eforce:1.> select m_ExtraInfo->geographicLocation from workingEntities.finalEntity where m_ExtraInfo->geographicLocation->latitude='41.03670138';
|eforce:2.> go
.
{
geographicLocation={
latitude='41.03670138';
locationDescription='Atatark Cultural Center Gamusuyu Mh 34437 Beyoulu Istanbul Turkey';
locationName='Atatark Cultural Center Gamusuyu Mh 34437 Beyoulu Istanbul Turkey';
longitude='28.98790969'
};
}

This is meant as a quick introduction to the data flow and I'll stop here. But be mindful of
ncim.entityData
ncim.collects
entitytype 111
ncim.mainNodeDetails
Take that entityId and you'll need to follow the path of that entityid in the tables above.
