Node Monitor has been an invaluable tool for us validators but we could use some more robust features. Ideally, if there could be a way to get a notification when a node is not in “latest” mode, so that we can be notified of unhealthy sync states without having to always check constantly.
Short of the team implementing this themselves in to node monitor, then perhaps an API for accessing “sync state” so that someone else can build an app or way to monitor the sync state and set up a notification (perhaps via telegram). Right now, I don’t believe there is currently an API available.
Right now other then checking manually, I only know of an unhealthy state when a node gets slashed and NITO BOT informs me, at which point I check node monitor and see that i have a big problem. And typically it is too late at that point to prevent 1 or more nodes from getting slashed.
