package execution_graph

Metrics contains all the timing metrics about a Node.

Used in: Node

int64 start_timestamp_millis = 1
The time when the node started, as milliseconds from the Unix epoch.
int32 duration_millis = 2
How long did this node last. This should be the sum of all the parts below, but is included separately to identify issues when that's not true.
int32 parse_millis = 3
int32 fetch_millis = 4
int32 network_millis = 5
int32 upload_millis = 6
int32 process_millis = 7
int32 setup_millis = 8
int32 process_outputs_millis = 9
int32 queue_millis = 10
int32 discover_inputs_millis = 14
int32 retry_millis = 11
Total time spent on failed attempts.
map<int32, int32> retry_millis_by_error = 12
Mapping from error code to the time spent on attempts that failed with that error.
int32 other_millis = 13
Time spent where we don't have more detailed information. This should be just duration_millis minus all the other parts, but it is kept separately to identify bugs in the code that produces the timing info.

Node is one entry in the executed graph.

string description = 1
All nodes should have a description so human debuggers could see what was going on in this step. This should be ActionAnalysisMetadata.prettyPrint().
int32 index = 2
The index is a unique (within a single build) but arbitrary identifier for this node. The same node will likely have different indexes across builds. For performance reasons, the set of all indexes in a build should be dense.
string target_label = 3
The target name. The field is not set if a spawn or action is shared between multiple targets or if it doesn't belong to any target. Note that a target can trigger several spawns, that can run in parallel or in sequence.
string mnemonic = 4
The spawn or action mnemonic. For example, Javac, GoLink, TestRunner, etc.
string rule_class = 10
The rule class for the above target. Examples: java_test, cc_library, etc.
optional Metrics metrics = 5
repeated int32 dependent_index = 6
A list of node indexes corresponding to direct dependencies of this node.
string runner = 7
The name of the spawn runner that ran the spawn, if applicable.
string runner_subtype = 8
Details about the runner.
int32 retry_of = 9
A node index that this is a retry of. For example, the second attempt of a flaky test would point to the first attempt, and the third attempt would point to the second.
