= 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 [http://genimon.uky.edu/ GENI Monitoring System].  

== 1.2 Steps for SCS Check ==

 1. Login into the [http://genimon.uky.edu/ 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 above 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 above 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.

== 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 [http://tamassos.gpolab.bbn.com/nagios3/ 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.
