Azure Cosmos DB for Apache Cassandra monitoring integration

Azure Cosmos DB for Apache Cassandra is suitable for storing data for applications designed for Apache Cassandra.

With Site24x7's integration, you can monitor your database with accurate metrics, configure thresholds, and get instant alerts if there is a breach.

Setup and configuration

Adding an Azure Cosmos DB for Apache Cassandra while configuring a new Azure monitor

If you haven't configured an Azure Monitor yet, add one by following the steps below:

  1. Log in to your Site24x7 account.
  2. Choose Cloud from the left navigation pane, and select Azure > Add Azure Monitor. You can also follow these steps to add an Azure Monitor.
  3. During Azure monitor configuration, in the Add Azure Monitor page, select Azure Cosmos DB for Apache Cassandra along with other required resource types from the Service/Resource Types drop-down. Check if you have configured the corresponding Resource groups and Tag filters in the Edit page.

Adding an Azure Cosmos DB for Apache Cassandra to an existing Azure monitor

If you already have an Azure monitor configured for the tenant, you can add the Azure Cosmos DB for Apache Cassandra using the following steps:

  1. Log in to your Site24x7 account.
  2. Navigate to Cloud > Azure > select the Azure monitor from the left pane for which you wish to add an Azure Cosmos DB for Apache Cassandra.
  3. In the Service View page, click the Enable Monitoring button in the Azure Cosmos DB for Apache Cassandra Service type. Check if you have configured the corresponding Resource groups and tag filters in the Edit page. 
Note

It will take 15-30 minutes to discover new Azure resources. To immediately discover the selected configuration, click Discover Now in the top-right corner, by doing which all the resources that match the filters configured in Azure Edit page will be discovered even if the Auto-Discover New Resources option is disabled. 

Now, you can view the discovered databases from the Service View dashboard itself.

Polling frequency

Site24x7's Azure Cosmos DB for Apache Cassandra monitor collects metric data every minute and the statuses from your applications every five minutes.

Threshold configuration

Associating a threshold profile can be done from the monitor Edit page:

Note

The changes done for this threshold profile will be applied to all the associated monitors. You can either add or edit the threshold profile by clicking the + or pencil icon respectively.

Bulk Action:

Bulk association of threshold profiles can be done from Admin page (Admin >  Inventory > Bulk Action > Under Monitor Configuration, go to Modify Threshold Profile).

You can set the threshold values for the metrics by selecting the Threshold and Availability option. You can also configure IT automation at the attribute level.

Default thresholds

Site24x7 alerts you based on a set of default thresholds. These default thresholds ensure that your database capacity is not overutilized, thus maintaining optimal storage and performance. This also helps in reducing costs. The default thresholds are provided for the below metrics:

  • Public Network Access Changed
  • Default Consistency Policy Changed
  • Service Availability
  • Normalized RU Consumption
  • Account Keys Updated
  • Region Removed
  • Cassandra Table Updated
  • Cassandra Table Deleted
  • Cassandra Keyspace Updated
  • Cassandra Keyspace Deleted

IT automation

Site24x7 offers a set of exclusive IT automation tools to auto-resolve performance degradation issues. These tools react to events proactively rather than waiting for manual intervention.

How to configure IT Automation for a monitor.

Configuration Rules

With Site24x7's Configuration Rules, you can set parameters like Threshold Profile, Notification Profile, Tags, and Monitor Group for multiple monitors. These rules can be configured and run for the existing or new monitors (during addition) matching the given criteria.

How to add a configuration rule.

Reports

Gain in-depth data about the various parameters of your monitored resources and accentuate your service performance using our insightful reports.

To view reports for an Azure Cosmos DB for Apache Cassandra:
