Use the Operations tab to: * Compare response time, throughput, and error rate across a service's operations. * Separate incoming, outgoing, and internal traffic to isolate where latency or errors originate. * Drill into a single operation to inspect its latency percentiles, success and error counts, and individual spans.

In your Coralogix toolbar, navigate to **APM**, then select the **Service Catalog** tab. 2. Select a service to open its drilldown, then select the **Operations** tab. 3. Use the **Operations Type** toggle to choose which traffic to view: **Incoming**, **Outgoing**, or **Internal**. The [environment filter](https://coralogix.com/docs/docs/user-guides/apm/features/environment-filter/.md) and any drilldown [dimensions](https://coralogix.com/docs/docs/user-guides/apm/features/service-catalog/.md#filter-the-drilldown-using-dimensions) scope the operations shown. ## Operation types[​](#operation-types "Direct link to Operation types") The **Operations Type** toggle scopes the whole tab to one class of traffic: * **Incoming**: requests the service receives, taken from server and consumer spans. * **Outgoing**: requests the service sends to other services, taken from client and producer spans. * **Internal**: operations internal to the service, taken from internal spans. ## Summary charts[​](#summary-charts "Direct link to Summary charts") Three charts at the top of the tab summarize the selected operation type: * **Response time**: response time across operations, with a percentile selector (P50, P75, P90, P95, P99, P99.99, P99.99999, or Avg). Use the series selector to plot all operations or the top 5, 10, or 20. * **Requests**: request volume. Use the chart dropdown to switch between **Requests/s** (default) and **Requests** (absolute count). The **Requests/s** option is hidden when APM is sourced from Events2Metrics. * **Errors**: error volume. Use the chart dropdown to switch between **Errors** (default), **Errors percentage**, and **Errors/s**. The **Errors/s** option is hidden when APM is sourced from Events2Metrics. When the service has no errors for the selected type, the chart shows a no-error state. Each chart has its own visualization and scale controls — see [Customize chart visualization](https://coralogix.com/docs/docs/user-guides/apm/features/service-catalog/.md#customize-chart-visualization). ## Operations table[​](#operations-table "Direct link to Operations table") The table below the charts lists every operation matching the selected type. By default it shows: * **Name**: the operation name. * **Method**: the request method, where applicable. * **P95**: 95th-percentile response time. * **Total Requests**: total requests over the selected timeframe. * **Errors/s**: errors per second. Hidden when APM is sourced from Events2Metrics. * **Errors%**: error rate as a share of total requests. * **Total Time Spent**: the operation's share of the service's total time, shown as a bar with the percentage and absolute time. The table is sorted by **Total Time Spent**, descending, by default. Select **Manage Columns** to add other columns — including **Requests/s** (Span Metrics only), other latency percentiles (**P99**, **P90**, **P75**, **P50**, **Avg**), **Throughput**, **Total Errors**, and **Errors Per Minute**. Use the search box to find an operation by name, and the comparison control to compare each operation's metrics against an earlier period (for example, 1 day or 7 days ago). ### Rank and filter operations[​](#rank-and-filter-operations "Direct link to Rank and filter operations") For a service with many operations, rank the table and narrow it to the operations you care about. These controls apply to incoming, outgoing, and internal requests. * **Top N selector**: Limit the table to the busiest operations. Select **Top 5** (default), **Top 20**, or **Top 100** to set how many operations the table returns. Your selection is preserved as you re-sort. * **Server-side ranking**: Select a metric column header — for example requests, errors, error rate, or a latency percentile — to rank all of the service's operations by that metric and return the top N. The operation and method columns reorder the rows already loaded. * **Operation-name filter**: Filter the table to specific operations, and the ranking is computed over your selection. Only operation names that have already appeared in the results are available to select. ## Investigate an operation[​](#investigate-an-operation "Direct link to Investigate an operation") Select an operation row to open its drilldown drawer, which summarizes the operation over the selected timeframe. The header shows the operation name and three key metrics — **Requests/s**, **P95 Latency**, and **Errors Rate** — and a **Go to Explore** link that opens the operation's spans in [Explore](https://coralogix.com/docs/docs/user-guides/data_exploration/spans/.md). The drawer includes: * **Latency**: latency over time by percentile (p99, p95, p75, p50, and avg). * **Successes and errors**: successful and failed requests over time, with the total success and error counts in the chart header. * **Spans**: a table of the individual spans for the operation, each with its timestamp, the transaction it belongs to, duration, and any error and error message. Use the search box to filter the spans, **Order by** to sort them, and **Reset filters** to clear the drawer's filters. Select a span to open the [trace](https://coralogix.com/docs/docs/user-guides/data_exploration/spans/.md) it belongs to for full context. ## Next steps[​](#next-steps "Direct link to Next steps") See how a service's operations combine into end-to-end flows in [Transactions](https://coralogix.com/docs/docs/user-guides/apm/features/transactions/.md), or analyze its downstream calls in [Dependencies](https://coralogix.com/docs/docs/user-guides/apm/features/dependencies/introduction/.md). ## Additional resources[​](#additional-resources "Direct link to Additional resources") * [Introduction to Application Performance Monitoring](https://coralogix.com/docs/docs/user-guides/apm/getting-started/apm-onboarding-tutorial/.md) * [Service Catalog](https://coralogix.com/docs/docs/user-guides/apm/features/service-catalog/.md) * [Explore spans](https://coralogix.com/docs/docs/user-guides/data_exploration/spans/.md)
