Although it’s nice to know that the jsErrLog service is sitting there recording errors that your users are seeing it does put the onus on developers to remember to check the report page for their URL to see if there have been any issues.
Because you might get a flurry of messages if you deploy a version and there’s an error, or a 3rd party component has a problem the bot also listens to a set of messages so it’s easy to suspect the alerting (or turn it back on when the problem has been fixed).
At the moment there a few restrictions:
· alerts have to match a specific URL
· for a given user all alerts are turned off/on (no per URL granularity)
· alerting is only available to users who’ve made a donation or promoted jsErrLog
The reason for the first one is a limitation with the way AppEngine lets me query data (unlike SQL the GQL query language does not support the CONTAINS or LIKE verbs)… I’m looking for a solution to that
The second is a feature that I plan to add soon depending on demand.
The third… at the moment it takes a little bit of setup to add new users so I’m adding it as the first freemium feature though this may change. If you want that enabled please let me know the URL you are monitoring and your Google Chat ID and I’ll let you know what else you need to do to enable it…
