Answer: An ALERT email is sent when one or more target database conditions match user-defined criteria.

The Alerts Criteria Page lets you turn alerts on and off and specify alert criteria for a particular target database. Individual criteria may include a threshold amount and/or a duration or waiting period.

The "Recent alert history" section of an ALERT email is a list of recent ALERT, ALL CLEAR and CANCELLED conditions for this target database.

The "Recent sample history" section of an ALERT email shows what the Foxhound History page looks like when the alert was issued, including blocked and current connections.

The sort order for the current connections section of an ALERT email depends on the alert condition, as follows:

Alert Email	Connection Sort Order	Connections Sorted On
1 - Database unresponsive	descending	CPU Time
2 - Long heartbeat	descending	CPU Time
3 - Long sample time	descending	CPU Time
4 - CPU usage	descending	CPU Time
5 - Database disk space	descending	Disk Writes
6 - Temp disk space	descending	Disk Writes
7 - Log disk space	descending	Disk Writes
8 - Other disk space	descending	Disk Writes
9 - Arbiter unreachable	descending	CPU Time
10 - Partner unreachable	descending	CPU Time
11 - HA failover	descending	CPU Time
12 - HA mode change	descending	CPU Time
13 - File fragmentation	descending	Disk Writes
14 - Waiting requests	descending	CPU Time
15 - Incomplete I/Os	descending	Disk Writes
16 - I/O operations	descending	Disk Writes
17 - Checkpoint urgency	descending	Disk Writes
18 - Recovery urgency	descending	Disk Writes
19 - Cache size	descending	CPU Time
20 - Cache satisfaction	ascending	Cache Satisfaction
21 - Temp file usage	descending	Temp Space
22 - Conn temp file usage	descending	Temp Space
23 - Blocked connections	descending	Conns Blocked
