aind_watchdog_service

Usage

Watchdog runs in the background (see deployment), and watches a directory for newly-created yaml files containing instructions to transfer files.

On a computer where the watchdog service is running, manifests can be submitted by creating a file in the right folder. To do this in your software, pip install aind-watchdog-service and use the aind_watchdog_service.models.ManifestConfig object to write your manifest file in the proper format. See the examples/ folder in this repo for more details.

Configuration

Watchdog is configured using SIPE's configuration zookeeper server. The configuration options are listed in /src/aind_watchdog_service/models/watch_config.py.

Monitoring

Watchdog logs can be monitored from the main SIPE logserver (http://eng-logtools:8080/?channel_filter=watchdog&hide=location,count) or this grafana dashboard.

Deployment

Deployment in the institute is handled by SIPE systems engineers, submit a SIPE Request if you need watchdog installed somewhere.

Github actions are used to compile aind-watchdog-service into an executable using pyinstaller. This executable is attached to a Github Release and uploaded to SIPE's software /releases storage, where it can be deployed to rigs in the institute.

Watchdog should be deployed on a SIPE-accessible rig via the install-aind_watchdog_service.yml ansible script. This will download the app and set up a windows scheduled task to run the service. By default, the scheduled task includes a nightly restart at 11:30pm. If the task is running, the scheduler will kill the old instance and start the new one - due to how task scheduler force kills processes, the death of an old process will not generate a stop log.

Testing

Watchdog has a bundled test function that will create some dummy data on the rig and create a manifest file to transfer that data. Once Run it with the below commands:

cd "C://Program Files/AIBS_MPE/aind_watchdog_service"
aind_watchdog_service.exe --test

It will print something like the following:

Data created at C:\ProgramData\AIBS_MPE\aind_watchdog_service\logs\test_data
Manifest created at C:\Users\svc_mpe\Documents\aind_watchdog_service\manifest\test_manifest_2024-11-15_17-31-25.yml

Make sure that the running instance of watchdog picks up the manifest and completes the transfer.
