Monitoring AWS DynamoDB

As mentioned earlier, eG Enterprise provides a specialized model for monitoring AWS DynamoDB (see Figure 1).

Figure 1 : Layer model of AWS DynamoDB

Each layer of Figure 1 above is mapped to tests that report a variety of metrics revealing the availability, replication, resource usage and much more!

Using these metrics, administrators can find quick and accurate answers to the following persistent performance queries:

• Are there too many tables with system errors?

• Are there too many user errors and system errors on the target server?

• Is the network connection available on the target server?

• Is the database is taking too much time to respond to a query?

• Whether the database connection is available or not?

• Is the database taking too much time to execute queries?

• Are there too many throttled requests, conditional check failed requests, and transaction conflict requests on the target server?

• Are there too many read and write throttled events?

• Are the read and write capacity units properly provisioned?

• Is the number and percentage utilization of read and write capacity units too high? If so, then how much?

• What is the consumption rate of read and write capacity units?

• What is the percentage of completion when a new global secondary index is being added to a table?

• Is the request latency too high?

• Is the age of old unreplicated records too high? If so, then how much?

• Whether or not replication enabled in the target server?

• Are there too many unavailable regions on the target server? If so, then how many?

• Are there too many pending replication by records on the target region?

• Is the replication region available? What is the region response time?

• Is the connection time to the replication region too high?

• Does the region take too much time to execute the query?

• Is the replication latency on the target region too high?
