Last updated: 2020-05-09 18:24:19

Tencent Cloud Monitor provides the following monitoring metrics for SCF:

Currently, two levels of monitoring metrics are supported. Monitoring metrics at the function level can be viewed in specific functions, while those at the region level can be viewed by selecting a specific region on the overview page to display the statistics of all function monitoring metrics.

Metric Name Parameter Description Unit Dimension
Execution duration duration The execution duration at the function or region level refers to the function code execution time from start to end, averaged by granularity (1 minute or 5 minutes). Milliseconds Function
Region
Number of invocations invocation The number of requests at the function or region level, summed by granularity (1 minute or 5 minutes). - Function
Region
Number of errors error The number of error requests after the function is executed, which currently includes those on the client side and on the platform, summed by granularity (1 minute or 5 minutes). - Function
Region
Number of concurrent executions concurrent_executions The number of requests processed concurrently at the same time point, summed by granularity (1 minute or 5 minutes) and determined by the maximum value at the function or region level. - Function
Region
Number of restricted requests throttle The number of requests that reaches the bandwidth limit at the function or region level, summed by granularity (1 minute or 5 minutes). - Function
Region
Execution memory mem The actual memory used by the function runtime, whose maximum value is calculated by granularity (1 minute or 5 minutes). MB Function
Time memory mem_duration Resource usage, which is calculated by multiplying the function execution duration by the execution memory, summed by granularity (1 minute or 5 minutes). MBms Function
Outbound traffic out_flow The outbound traffic generated by accessing resources on the public network from a function, summed by granularity (1 minute or 5 minutes). KB Function
System internal error (HTTP 5xx) syserr The number of 5xx status codes returned after function execution, summed by granularity (1 minute or 5 minutes). - Function
Function error (HTTP 4xx) http_4xx The number of 4xx status codes returned after function execution, summed by granularity (1 minute or 5 minutes). - Function
Successful invocations (HTTP 2xx) http_2xx The number of 2xx status codes returned after function execution, summed by granularity (1 minute or 5 minutes). - Function
Resource limit exceeded (HTTP 432) http_432 The number of 432 status codes returned after function execution, summed by granularity (1 minute or 5 minutes). - Function
Function execution timed out (HTTP 433) http_433 The number of 433 status codes returned after function execution, summed by granularity (1 minute or 5 minutes). - Function
Memory limit exceeded (HTTP 434) http_434 The number of 434 status codes returned after function execution, summed by granularity (1 minute or 5 minutes). - Function
