Our Serverless Monitoring feature provides customers using the Coralogix AWS Lambda Telemetry Exporter with the ability to better control and understand your lambda servers on both macro and granular levels.
Feature
For each lambda function, view its triggers, the AWS account to which the function belongs, region, runtime, invocations, errors, timeouts, last invocation, average latency, and whether the function is out of memory.
Prerequisites
In order to use the Serverless Monitoring feature, you must first set up the following:
STEP 1. From your navigation pane, click APM. Select the Serverless tab.
STEP 2. Select the timeframe for which you want to view information.
STEP 3. Select a function to view the drill down.
Drill Down
Clicking on a specific function provides you with more in-depth information about it.
The drill down shows the metadata of the lambda function being examined, including several graphs, as well as the breakdown of when the function was triggered and how.
Invocations
The INVOCATIONS graph presents an aggregative breakdown of how often the function was triggered. Each bar in the graph shows the number of invocations, errors, and timeouts for a segment of time (the exact length of time is calculated dynamically depending on the time range shown).
Cold Start Frequency
The COLD START FREQUENCY graph presents you the frequency of cold starts over time. Cold starts occur when the function is triggered and has to start from scratch (in contrast with invocations where the function is woken up from a sleep state).
Duration
The DURATION graph presents you with the length of time a function ran. It includes both invoked lambdas and cold starts and allows you to see the time taken for each.
Memory
The MEMORY graph presents how much memory was used by the triggered lambda function.
Related Data
Clicking on a specific invocation of the lambda function brings you to the Related Data page. This page shows the lambda function together with the chain of actions that occurred before and after it was triggered.
The left-hand pane presents the trace view, while the right-hand pane presents information about the lambda function (such as triggers, resources, events, logs, tags, etc.).
