Software Update Deployment Process with log files

At a high level the ConfigMgr client agent performs these 2 client actions to scan, install and report status of any targeted updates.

Software Updates Scan Cycle

Software Update Deployment Evaluation Cycle

  1. Software Update Scan Cycle:

During this process Client will start scanning against the Software Update Point (SUP) and populate the local Software Update related WMI classes with status of each Applicable CIs for the BulletinID as Required. The status or information about non-applicable CIs will not be stored locally by the client. Upon completion of scan cycle, the client will send a state message to Management Point, which in turn is processed at the site server and forwarded upstream until it reaches the Central Site Server. This scan cycle is run as per the preset interval in the Software Update Component configuration of your site.

Details about the state message on completion of successful scan cycle are reported with state message ID as 501 and the data is stored in Update_ScanStatus table.

 2. Software Update Deployment Evaluation Cycle:

After the Software Update deployment is targeted and the evaluation cycle is triggered, the client will download and install the required updates. Upon successful completion of installation, the client sends the state message (ID: 301) to the Management Point.  Like the scan state message, this message is also processed at the site server and replicated up the hierarchy.

When we Deploy software updates to SCCM Client what will happens in the client side. Here is the complete flow with logs:

Once software updates are deployed to SCCM client, below mentioned actions will takes place at the client side and respective logs will be written respectively as per the flow:-

  1. Update Evaluation will be triggered either manually or via scan schedule.

  8. Updatesstore.log – Updatestore called to Adjust setting on WMI as needed
  9. Updatesdeployment.log – Updates deployment wakes up to begin CI evaluation and installation.
  10. CIAgent.log – CI agent start-up to check targeted CIs and download if necessary.
  11. Updatesdeployment.log – UpdatesDeploymnet calls Updates handler to initiate patch install.
  12. Updateshanlder.log – Updates handler call WUA handler to facilitate patch install.
  13. WUAhanlder.log – WUAhanlder coordinates with execmgr during patch install process
