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 into the GENI Monitoring System.
  2. Type "scs" in the top left hand Search box. This will show results in the main panel.
  3. Select "scs-geni". This will show details in the main panel.
  4. Scroll down to "Aggregate Availability". This graph show a value of 1 for up and 0 for down.

1.3 SCS Check - Pass Criteria

If step 4 shows 1, than check passes. A value of 1 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 0, than the check fails. A value of 0 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 Problems in the left hand navigation bar.
  3. search for ???, and review status reported.

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.
