Possible metric types that can be tracked on a given resource.
Metric Type | Data Type | Description | ||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
AggregatedMetric |
Object
|
Allows for aggregating existing metrics over a period of time. Useful for running sums or averages; also for extracting single data item from collection-based metrics | ||||||||||||||||||||||
AmazonCloudWatchMetric |
Double
|
Tracks Amazon CloudWatch metrics using latest AWS API - more info is here. | ||||||||||||||||||||||
DatabaseActiveSessionCount |
Double
|
Tracks the number of open sessions for the given database. | ||||||||||||||||||||||
DatabaseSize |
Double
|
Tracks the size of the database in megabytes. | ||||||||||||||||||||||
DatabaseSqlBlockingQueries |
|
Tracks queries that are currently blocking each other, with specific SQL and session IDs. | ||||||||||||||||||||||
DatabaseSqlBlockingQueryCount |
Int32
|
Tracks the number of deadlocking queries. | ||||||||||||||||||||||
DatabaseSqlConnections |
|
Tracks currently open connections and their associated information (host, username, etc) to the monitored database. | ||||||||||||||||||||||

DatabaseSqlNumeric |
Double
|
Tracks numeric value from custom user-defined SQL statement. | ||||||||||||||||||||||
DatabaseSqlQuery |
Object[]
|
Tracks a table-based collection of data retrieved via user-defined SQL statement. | ||||||||||||||||||||||
DatabaseSqlTopQueries |
|
Tracks top 10 (by combined utilization) queries and their associated information (SQL, utilization, etc). This metric can help DBAs optimize ineffective queries. | ||||||||||||||||||||||
DerivedMetric |
Double
|
Allows for deriving new metrics from existing ones. Useful for combining existing metrics together or for multiplying metrics by a factor | ||||||||||||||||||||||
LinkedMetric |
Object
|
Allows for tracking of metrics from other resources. Useful when it is important to evaluate metrics from different resources side-by-side | ||||||||||||||||||||||
ResourceStatus |
String
|
Tracks overall status of the resource. This is an important metric as it is used to drive Uptime reports. Possible values: Ready, Down, Unknown and in some cases Stopped | ||||||||||||||||||||||
ResponseTime |
Double
|
Measures time to connect to resource | ||||||||||||||||||||||
WindowsPerformanceCounter |
Double
|
Tracks performance counters defined as individual metrics. Any performance counter might be tracked. | ||||||||||||||||||||||
WindowsPerformanceCounterMultiInstance |
|
Tracks multi-instance performance counters. It returns an array of PerformanceCounterInstance objects for each counter instance. |
Possible commands that can be executed on a given resource. Ultimate subscription is required.
Command Type | Description | |
---|---|---|
CustomSqlDatabaseScript | Runs custom SQL script on specified database | |
WebRequest | Runs custom WebRequest to specified URL |
CloudMonix provided default monitoring templates.
Metric Name | Metric Type | Description |
---|---|---|
BlockingQueries | DatabaseSqlBlockingQueries | Disabled by default. Tracks queries that are blocking each other (metric disabled by default because it can add load to the database) |
BlockingQueryCount | DatabaseSqlBlockingQueries | Tracks blocking (possibly dead-locking) queries |
ConnectionList | DatabaseSqlConnections | Tracks the list of open connections against the database. This metric is a multi-dimensional array |
ConnectionsActive | DatabaseActiveSessionCount | Tracks number of open connections to the database |
Cpu | AmazonCloudWatchMetric | Average value of CPU utilization for the monitored SQL Amazon database |
QueriesInProgress | DatabaseSqlCurrentQueries | Tracks currently executing queries |
ReadIOPS | AmazonCloudWatchMetric | Tracks Read IOPS of current database instance |
ResponseTime | ResponseTime | Tracks resource's response time. Metric measures how long it took to open an active connection to SQL Amazon database in milliseconds |
Size | DatabaseSize | Tracks database size in MBs |
Status | ResourceStatus | Tracks the overall readiness status of the monitored resource. Possible values are: Ready, Down, Stopped and Unknown |
TopQueries | DatabaseSqlTopQueries | Tracks top 10 (by highest worker time) queries. Query text display is limited to 100 characters |
WriteIOPS | AmazonCloudWatchMetric | Tracks Write IOPS of current database instance |
Alert Name | Expression | Severity | Description |
---|---|---|---|
Blocking Queries |
BlockingQueryCount > 0
|
Warning | Raises an alert when blocking queries are detected for 5 minutes sustained |
Database Approaching Max Size |
Size > 1900
|
Warning | Disabled by default. Fires an alert when the size of the database approaches maximum service limit. Customize this alert with proper threshold according to specific database tier, before enabling it. More information on maximum service limits here: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Limits.html#RDS_Limits.Limits |
High Utilization |
Cpu > 80
|
Warning | Raises an alert when either CPU utilization, data reading utilization or log-writing utilization is over 80% for 5 minutes sustained |
Open Sessions Approaching Max Limit |
ConnectionsActive > 275
|
Warning | Disabled by default. Number of open connections (sesssions) is approaching maximum limit. Change the threshold in accordance to your database tier. More information here: https://sysadminxpert.com/rds-max-db-connection-limits-as-per-db-instance-type/ |
Resource Outage |
Status == "Down"
|
Error | Raises an alert when connectivity cannot be established, after specified number of retries on the Advanced tab for sustained period of time |
Slow Response |
ResponseTime > 15000
|
Warning | Raises an alert if establishing a connection to monitored resource takes over 15 seconds for sustained period of time |
