Operation Example
Open External URL
Scenario: Analyze the CLB access log dashboard to identify the CLB instance with the highest failure rate, and navigate to the corresponding CLB instance to view instance details and make configurations.
In the TOP10 Instance Request Failure Rate (%) chart, choose Interaction Event > Open External URL. The ${__row.lb_id} in the URL to navigate to is a variable, which is configured as follows:
After configuration, click the corresponding lb_id to navigate to the instance details page.
Searching for Other Log Topics
Scenario: The TOP error rates for server IP addresses have been identified. When an IP address with a high error rate appears, navigate to the search and analysis page to view logs for that IP address where the status code is 4XX.
In the chart, configure Interaction Event> Search For Other Log Topic, choose to use the current log topic, and configure the search statement as shown in the following figure:
server_addr:${__value.raw} AND status:[400 TO 499]
Click the target IP address to automatically open the search page and display the search results.
Adding to Filter
Scenario: When viewing log content in a table, you can click any field to add it to the filter, facilitating drilling down during browsing. Configure the Add to Filter feature as follows:
${__field.name}:${__value.raw}
After configuration, you can click any field value to add it to the filter.
Opening a Dashboard
Scenario: View the "Overview" dashboard to identify the cluster with the highest number of errors. Then, using that cluster ID as a filter, open the "Abnormal Event Aggregation Search and Analysis" dashboard to view details. Configure as follows:
clusterId:${__row.cluster}
After configuration, click the corresponding cluster field. This action will navigate to and open the Abnormal Event Aggregation Search and Analysis dashboard, where the metrics for that cluster are already filtered.
