Graph metrics

Metrics for monitoring DSE Graph with dashboard graphs and alerts in OpsCenter.

Reference of available graph metrics in OpsCenter monitoring for DSE Graph. Alerts are also available for all Graph metrics.

Metrics for monitoring DSE Graph in OpsCenter include:
  • Cache metrics: Cache metrics bound to a specific DSE graph. Per node per graph instance metrics.
  • Request Latencies: Histogram of request latencies.
  • Threadpool metrics: Global-level threadpool metrics for tasks that have active, pending, and completed threads.

Graph cache metrics

Metrics for hits and misses to the adjacency and index caches used by DSE Graph.
Note: The graph must be configured at schema creation time to use the adjacency or index caches. For more information, see caching.
Graph Classic: Adjacency Cache Hits [graph-adjacency-cache-hit]
Number of hits against the adjacency cache for this graph.
Graph Classic: Adjacency Cache Misses [graph-adjacency-cache-miss]
Number of misses against the adjacency cache for this graph.
Graph Classic: Index Cache Hits [graph-index-cache-hit]
Number of hits against the index cache for this graph.
Graph Classic: Index Cache Misses [graph-index-cache-miss]
Number of misses against the index cache for this graph.

Graph transaction latencies

Graph Classic: Request Latencies [graph-request-latencies]
The min, median, max, 90th, and 99th percentile of request latencies during the period.

Graph threadpool metrics

Graph query threads, Graph scheduled threads, Graph system threads, and Graph Gremlin worker metrics for pending, active, and completed threads in the respective threadpools. Threadpool metrics are global across all graphs.

Graph Classic TP: Graph Scheduled Threads Pending [pending-graph-scheduled-threads]
Number of pending tasks in the GraphScheduledThreads thread pool.
Graph TP: Graph Scheduled Threads Active [active-graph-scheduled-threads]
Number of active tasks in the GraphScheduledThreads thread pool.
Graph Classic TP: Graph Scheduled Threads Completed [completed-graph-scheduled-threads]
Number of tasks completed by the GraphScheduledThreads thread pool.
Graph Classic TP: Graph System Threads Pending [pending-graph-system-threads]
Number of pending tasks in the GraphSystemThreads thread pool.
Graph Classic TP: Graph System Threads Active [active-graph-system-threads]
Number of active tasks in the GraphSystemThreads thread pool.
Graph Classic TP: Graph System Threads Completed [completed-graph-system-threads]
Number of tasks completed by the GraphSystemThreads thread pool.
Graph Classic TP: Gremlin Worker Threads Pending [pending-gremlin-worker-threads]
Number of pending tasks in the GremlinWorkerThreads thread pool.
Graph Classic TP: Gremlin Worker Threads Active [active-gremlin-worker-threads]
Number of active tasks in the GremlinWorkerThreads thread pool.
Graph Classic TP: Gremlin Worker Threads Completed [completed-gremlin-worker-threads]
Number of tasks completed by the GremlinWorkerThreads thread pool.

Dashboard Graphs for Graph Metrics

Dashboard graphs are available for all Graph metrics in OpsCenter. Click Cluster > Dashboard > Add Graph. Select the metric from the Metric list in the Add Metric dialog:

Add graph metric dialog

The Graph list is only applicable to the per graph cache metrics.

After adding metrics and clicking Save Graph, the graphs appear on the monitoring dashboard.
Tip: Clone the Default preset tab and give it a name such as DSE Graph to organize your dashboard.

Graph Alerts

Alerts are available for all graph metrics. Click Alerts > Notify me when > Advanced > Graph > Graph metric in the Add Alert dialog.

Alerts Advanced Graph menu

Define the notification criteria for each alert required for monitoring your DSE Graph environment.
