🌳 Call Tree​

The Call Tree helps efficently visualize and navigate the call stack in Salesfroce Apex debug logs. Learn to expand and collapse method calls, sort and filter by execution metrics, and quickly jump to code locations in Visual Studio Code. Enhance your Salesforce debugging and performance analysis with detailed insights into DML, SOQL, and execution times.

Call Tree Screenshot displaying an expandable and collapsible call stack with event types, method signatures, timing metrics, and aggregated DML, SOQL, Throws, and Row counts.

Each row shows event type, details such as method signature, self and total time as well as aggregated DML, SOQL, Throws and Row counts.

View Modes​

The Call Tree supports three separate views, toggled via the toolbar:

  1. Time Order (default) Displays the call stack in chronological execution order. Best when you want to follow the exact sequence of events from top to bottom.
  2. Aggregated Groups repeated method paths so repeated executions are combined. Best when you want a condensed hotspot view without reviewing every individual frame occurrence.
  3. Bottom-Up Starts with each callee as the root and expands into callers. In this view, roots are callees and expanded rows are caller context. Best when you want to find which methods are hogging the most time and see the different caller paths that led to them.

The Call Tree's three view modes side by side: Time Order, Aggregated and Bottom-Up.

Go to Code​

Clicking the link in the event column will open the corresponding file and line, if that file exists in the current workspace.

Sort​

Each column can be sorted by clicking the column header, this will sort the rows within the tree structure e.g sorting by self time will sort the children within a parent with the largest self time to the top but only within that parent.

Column Views​

Switch column sets from the Columns button in the toolbar (or the header right-click menu):

  1. General - everyday overview: DML/SOQL counts + rows, throws, and total/self time.
  2. Time - call count and self/total/average time.
  3. Governor Limits - DML/SOQL/SOSL counts + rows, throws, heap peak, and governor limit usage (avg + peak).
  4. Database - DML/SOQL/SOSL counts + rows, with total/self time to show which query-heavy path is slow.
  5. Memory - heap net (retained), gross (churn) and peak live heap, each total + self.

Show or hide individual columns from the same menu; an edited view shows a reset icon. Choices persist per view. Type (the raw log event type) is hidden by default in every view and can be turned on here - names read better without it, but it sorts, groups and exports like any other column.

The view you switch to is remembered, so the tables reopen the way you left them.

Heap analysis​

The Memory view carries three heap metrics per call path - net (retained), gross (churn) and peak (highest live heap) - each with a total and self variant. See Governor limits + heap for how to read them together.

Filtering​

  1. Details - events with 0 time are hidden by default; toggle to show them (all views).
  2. Debug Only - show only debug statements (Time Order and Aggregated).
  3. Type - keep a single event type (Time Order and Aggregated).
  4. Namespace - keep one or more namespaces from the dropdown.
  5. Total Time / Self Time - set a min-max range.

SOQL Formatting​

SOQL and SOSL query rows are reformatted onto multiple lines and syntax highlighted, so keywords, fields and bind variables are easy to read at a glance.

Keyboard Navigation​

The Call Tree can be navigated with the keyboard. The up and down keys will move between rows, the left and right keys will expand and collapse a parent within the tree.

Inspect a row​

Selecting a row fills the inspector with that call path - its governor metrics, the stack that led to it, and a call tree scoped to just that row, which you can read in Time Order, Aggregated or Bottom-Up independently of the tab's own view mode.

Category Coloring​

The Name column is colored by each event's category - Apex, Code Unit, System, Automation, DML, SOQL, Callout and Validation - using the colors of the active timeline theme, so the Call Tree and the Timeline themes stay visually consistent.

By default a small color chip is shown against each row. To color the full cell instead (background tint and colored text), enable Settings → Apex Log Analyzer → Colorize Call Tree category names.

Colors follow the active timeline theme and update instantly when you switch themes via Log: Timeline Theme.
