# Pacemaker ShowScores for SLES12 and SLES15
This program tries to show the scores each pacemaker resource has on cluster members (nodes).
See also the SUSE TID (no default-resource-stickiness)
NOTE: This program is *not* limited to two-node clusters (see examples below) like all the other scripts that I am aware of!
## Motivation
In SLES12 and SLES15 commands and their output changed, so a new simplified showscores was _invented_! :sparkles:
Original idea and script for older pacemaker versions (1.x) was done around 2009 by Dominik Klein.
In the sub-directory **SLES11** you will find a slightly enhanced and adapted version of Dominik original idea that runs **only on SLES11** pacemaker clusters.
## Requirements
This `showscores` version will **not** run under SLES11 because there the standard (G)AWK version is too old (GNU AWK 3.1.8) to support multidimensional arrays (please use instead the `showscores` version found in the SLES11 sub-directory). On the other hand SLES11 is meanwhile End-Of-Support/End-Of-Life (EoS/EoL).
It will run under SLES12SP5 = GNU AWK 4.1.8 (API: 1.0), SLES15SP2 = GNU AWK 4.1.0 (API: 1.0) and SLES15SP3/SP4/SP5 = GNU AWK 4.2.1 (API: 2.0)
## Example Output SLES15, 2 node cluster
``` shell
$ ./showscores
rsc_defaults: resource-stickiness=123 migration-threshold=5
## [ Resource ]#####[ Nodes -> ]## sap12ha1 sap12ha2

## Example Output, SLES15, 3 Node SAP HANA SRA cluster, read-enable setup
``` shell

Showscore taken on node: hanode_mm at Wed Apr 12 12:13:08 CEST 2023
```
NOTE: hanode_mm is the "Majority Maker" node and the rsc_defaults output is affected by "Bug 1210614 - Duplicated entries for resource-stickiness"
## Example Output SLES15, 3 Node SAP HANA SRA cluster, read-enable setup - wrong stickiness/threshold
``` shell
rsc_defaults: resource-stickiness=1 migration-threshold=3
##[ Resource ]#####[ Nodes ]## majority-maker node01 node02
