Manage SLOs

All created SLO tasks can be viewed under Monitors > SLOs. The list displays real-time metrics such as associated monitors, targets, downtime, compliance rate, error budget, etc. It also supports enabling, disabling, editing, viewing events, and exporting to dashboards.

List Fields

Field
 Description
Monitor The number of monitors associated with the SLI, which measures service performance.
Target The target percentage of service availability set when creating the SLO task.
Compliance Rate (7 days) The percentage of time the system was free of anomalies within the given assessment period (Compliance Rate = System Anomaly-Free Time / Assessment Period * 100%):
  • When the minimum target percentage <= percentage < target percentage, the SLA is considered unhealthy, displayed as an orange compliance rate;
  • When percentage < minimum target percentage, the SLA is considered non-compliant, displayed as a red compliance rate.
    		•
    Downtime (7 days) The time the monitor was in an abnormal state / used quota.
    Error Budget (7 days) The remaining fault-tolerant time for the current SLO (assuming the target SLO is set to 95%, meaning there is a 5% fault tolerance rate, defaulting to the last 7 days as the cycle, i.e., default: Error Budget = 7 days * 5% = 8.4h), displayed as:
  • Green: Remaining fault-tolerant time >= 0;
  • Red: Remaining fault-tolerant time < 0.
    		•

    Operation Instructions

    • Search: Filter by SLO name;
    • Batch: Enable/disable/delete multiple SLOs;
    • Single SLO task: Enable, disable, edit (except name/target/frequency), delete;
    • Delete: Supports deleting existing SLO tasks;
    • View related events: One-click view all unresolved events triggered by this SLO;
    • Export to dashboard: Synchronize the SLO view to the dashboard.
    Note
    • Deleting an SLO will also delete its dashboard view;
    • The time range of the SLO view in the dashboard defaults to be consistent with the dashboard, and the list defaults to show the compliance rate for the last 7 days.

    Retrieve SLO via DQL Expression

    Reference the following query for anomaly time:

    df_slo_cost represents deducted minutes, and summing the values gives the anomaly time. Replace df_slo_id accordingly:

    E::`slo`:(sum(`df_slo_cost`)) { `df_slo_id` = 'monitor_6bad2a76dd9b41d7894f21a76d44ae42' }

    To query the SLO value for 7 days, the DQL expression is as follows:

    eval((10080-A)/10080 *100, A="E::`slo`:(sum(`df_slo_cost`)) { `df_slo_id` = 'monitor_6bad2a76dd9b41d7894f21a76d44ae42'}")

    Example:

    In the image below, the anomaly time SLO value for the SLO task over the past 7 days is 80.496%.

    Go to Shortcut > Query Tool, select DQL Query, and enter the query statement for the 7-day SLO value. The query result matches the value in the image above.

    Note

    When using the Query Tool > DQL Query, ensure the time range in the top right corner matches the time range for retrieving the SLO value; slo_id can be viewed in Events > Event Details:
