Log or notify about events
Sometimes it would be interesting to have important events logged (or admin notified):
- if you run a wiki in a security sensitive context you might want to get notified if someone tries to hack into the system:
- new accounts created
- failed logins
- denial by ACL(?)
- other (non-security) important system events:
- running out of disk space
- tracebacks happened
- high load (although this is maybe rather for general server monitoring) or rather high moin page request rate
- users / IPs getting blacklisted by surge protection
