Usage

Watchdog runs in the background, and watches a directory for newly-created yaml files containing instructions to transfer files. To use, 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

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.

When deploying on a new rig that had previously had the non-SIPE version of watchdog installed, extra care must be taken.

• First, delete any scheduled tasks relating to watchdog. Some of these may be in a folder called "GUI Automation" or "AIND".
• Next, run tasklist to check if there active watchdog processes, and kill them all with repeated use of taskkill /F /PID pid_of_the_process.
  • One running instance of watchdog will have two processes listed by tasklist
• Install the new watchdog via ansible and check for a start log.
• SSH in and run a self test with aind_watchdog_service.exe --test (see below) and make sure you see successful logs.

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.

Development

After cloning the repo, watchdog can be installed from source with pip install .[service], and run with python src/aind_watchdog_service/main.py.
