CHK-003 GENI Network Stitching Checks

This procedure defines how GENI Network Stitching status can be verified. Checks to be verified include:

  • Status of the Stitching Computation Service (SCS)
  • Status of the GENI Stitching Sites

1.0 GENI SCS Check

1.1 Goals of SCS Check

The SCS is a service that provides stitching path information for known sites. This section defines to verify that the SCS is up and providing path information for the expected stitching sites. All information is found in the GENI Monitoring System.

1.2 Steps for SCS Check

  1. Login to GPO Nagios System
  2. Select Host Groups->Summary in the left hand navigation bar.
  3. Look for GENI Stitching Computation Services, and select the `"Host Status Summary" for the SCS check.
  4. The resulting page show the scs-geni status, which can be UP or DOWN.

1.3 SCS Check - Pass Criteria

If step 4 shows UP, than check passes. A value of IP means that the SCS service is running and answering a listaggregates request. The monitoring system also verifies that the list of aggregates returned includes the expected sites.

1.4 SCS Check - Fail Criteria and Escalation

If step 4 shows DOWN, than the check fails. A value of DOWN means that the SCS system is either not responding or responding with the wrong list of site aggregates.

Escalation: SCS issues should be escalated to GMOC.

2.0 GENI Stitching Sites Check

2.1 Goals of Stitching Sites Check

The Stitching Site check verifies that the SCS knows all path combinations between all aggregates that support stitching. This check does no actually verify that the paths are able to exchange traffic over the paths at this time.

2.2 Steps for Stitching Sites Check

Nagios alerts are available for failed checks of stitching paths. Alerts can be found as follows:

  1. Login to GPO Nagios System
  2. Select Host Groups->Summary in the left hand navigation bar.
  3. Look for GENI Stitching Computation Services, this should show as

2.3 Stitching Sites Check - Pass Criteria

If status is ??? than there are no path checks failing.

2.4 "Stitching Sites Check - Fail Criteria and Escalation

If ??? shows status as pending than check path function failed.

Escalation: SCS path issues should be escalated to GMOC.
