Thresholds provide a way to trigger events when different measurements exceed a given value. Thresholds configured at the node level can override Domain Thresholds.
Field Name | Description |
---|---|
Status |
|
nodes::configure::thresholds
permissions.To configure thresholds at the node level:
Load thresholds measure the health of the node itself.
Metric Type | Description | Default Value |
---|---|---|
CPU Usage | Monitors percent of CPU usage across all cores | 95% for 10 minutes |
Memory Usage | Monitors percent of total memory (RAM) used | 90% for 30 minutes |
Disk Usage | Monitors percent of total disk usage for the root partition | 80% for 1 minute |
Embrionic Flows | Monitors the number of TCP flows (connections) that are in the embryonic state (waiting for ACK) | none |
JVM Heap | Monitors the percent of allocated JVM memory used | none |
Field Name | Description |
---|---|
Name | The name of the threshold. This will be available in generated events. |
Telemetry | The metric to monitor. Options are CPU usage (%), memory usage (%), disk usage (%), and embryonic flows (absolute count). |
Threshold | The value that must be exceeded for an event to be generated. |
Duration | The time period to measure. If the threshold is exceeded for this duration, an event will be generated. |
Network thresholds measure the health of the network from the node’s perspective.
Metric Type | Description | |
---|---|---|
Latency (ms) | Monitors the round trip tunnel latency between this node and the target | |
Bandwidth IN Usage (Mbps) | Monitor the amount of received bandwidth on the specified interface | |
Bandwidth Out Usage (Mbps) | Monitors the amount of sent bandwidth on the specified interfaces |
Field Name | Description |
---|---|
Name | The name of the threshold. This will be available in generated events. |
Telemetry | The metric to monitor. Currently only latency (measured in milliseconds) is available. |
Threshold | The value that must be exceeded for an event to be generated. |
Duration | The time period to measure. If the threshold is exceeded for this duration, an event will be generated. |
