Upgrading the Cloud services sensors

The sensors in earlier versions of the Cloud services are no longer valid in the 1.1.4 version. Therefore, you must change the sensors after upgrading to Cloud services version 1.1.4 from either 1.1.3.x or 1.1.2.x version as described below.

You must know which sensors are configured and active.

Perform the following steps to upgrade the sensors:

Remove configuration of the old sensors by issuing the following commands:

mmperfmon config delete --sensors MCStoreGPFSStats

mmperfmon config delete --sensors MCStoreIcstoreStats

mmperfmon config delete --sensors MCStoreLWEStats

Remove the old sensors files from the /opt/IBM/zimon folder of every Cloud services node:
- ```
rm MCStoreGPFSStats.cfg
```
- ```
rm MCStoreIcstoreStats.cfg
```
- ```
rm MCStoreLWEStats.cfg
```
Copy the following sensor files from the /opt/ibm/MCStore/config/ folder to the /opt/IBM/zimon folder:
- TCTDebugDbStats.cfg
- TCTDebugLweDestroyStats.cfg
- TCTFsetGpfsConnectorStats.cfg
- TCTFsetIcstoreStats.cfg
- TCTFsGpfsConnectorStats.cfg
- TCTFsIcstoreStats.cfg

On each Cloud services server node, create a new MCStore-sensor-definition.cfg file under /opt/IBM/zimon/ and copy the following sensors text into it:

sensors=   
  {
     #Transparent cloud tiering statistics
     name = "TCTDebugDbStats"
     period = 10
     type = "Generic"
   },

  {
    #Transparent cloud tiering statistics
    name = "TCTDebugLweDestroyStats"
    period = 10
    type = "Generic"
  },
  {
     #Transparent cloud tiering statistics
     name = "TCTFsetGpfsConnectorStats"
     period = 10
     type = "Generic"
   },

  {
    #Transparent cloud tiering statistics
    name = "TCTFsetIcstoreStats"
    period = 10
    type = "Generic"
  },
  {
     #Transparent cloud tiering statistics
     name = "TCTFsGpfsConnectorStats"
     period = 10
     type = "Generic"
   },

  {
    #Transparent cloud tiering statistics
    name = "TCTFsIcstoreStats"
    period = 10
    type = "Generic"
  }

Specify the following command to register the sensors:

mmperfmon config add --sensors MCStore-sensor-definition.cfg

Specify the following command to verify that all the sensors are added:

mmperfmon config show

The system displays output similar to this:

- ```
service pmsensors restart
```
- ```
service pmcollector restart 
```
Verify the status of your pmsensors and pmcollector on the nodes:
- ```
service pmsensors status
```
- ```
service pmcollector status
```
