View MetricBase database status

View the status and health of the connection to your MetricBase database.

Before you begin

Role required: clotho_admin

Procedure

1. Navigate to All > MetricBase > MetricBase Health Dashboard.

2. In the list, select Health.

3. View the status of the database connection.

   If the database is offline, contact Customer Service and Support.

4. Monitor the lag time between your instance and the database by viewing the MetricBase Lag Statistics value.

   If the lag time is reported in multiple seconds, contact Customer Service and Support.

5. Select Refresh to view the latest status.

View MetricBase data usage and efficiency

Monitor the usage and efficiency of your MetricBase time series data.

Before you begin

Role required: clotho_admin

Procedure

1. Navigate to All > MetricBase > MetricBase Health Dashboard.

2. In the list, select Series.

   The MetricBase Series Information page displays the Total Series Count, which is the total number of series registered in MetricBase.

3. Determine whether any series aren't being used by calculating the stale series ratio.

   This ratio is the percentage of series that haven't received a value within a specified number of days.

   1. Enter the number of days (greater than or equal to 1) in the Staleness Time Period field.

   2. Select the Refresh icon (

The closer the ratio is to 0%, the fewer unused series there are within the given time period. You determine your own threshold for an acceptable stale series ratio. To lower the ratio, adjust the metric's sampling schedule or remove unused metrics or series. For help with removing a stale series, contact Customer Service and Support.

1. Determine how efficiently your time series data is used by viewing the Data Utilization Efficiency value.

   The value is the percentage of data points per metric that have a non-null value. The closer this value is to 100%, the fewer null data points there are. To increase the efficiency, review each metric to ensure that data is being posted at a similar rate to the first schedule of its retention policy. See MetricBase retention policies for more information.

2. Determine how often values are published to MetricBase by viewing the Average Unutilized Data Gap value.

   The gap value is the average number of entries between two non-null data points. To decrease the gap value, change the metric's schedule to publish data more often or update the metric's sampling period in its retention policy. See MetricBase retention policies.

View MetricBase statistics and metrics

You can view the status of the MetricBase database.

Before you begin

Role required: admin

Procedure

1. View the status of the MetricBase instance.

   1. Navigate to System Diagnostics > Stats > Stats.

   2. Scroll down to find MetricBase Statistics

1. View the metrics monitored by MetricBase and statistics about them.

   1. Click MetricBase > MetricBase Status

      The MetricBase Status page displays all of the metrics tracked in MB.

2.  Click the gear icon.

    The Personalize List Columns dialog box displays.

3.  Select and move metrics from the **Available** column to the **Selected** column to display the metric and click **OK**.

Debug MetricBase

You can display the results of debugging scripts in MetricBase.

Before you begin

Role required: admin

Procedure

1. Navigate to All > System Diagnostics > Session Debug > Debug MetricBase.

   When the page you are on submits queries to MetricBase, you see the transforms and how long they took on the bottom of the page. Submitting a lot of MetricBase queries may slow down the page load time significantly.

2. To view a history of the debug script's execution, click available here.

3. Click Update.

   Session debug tracking for MetricBase activities starts and the MetricBase Status page displays.
