🔇 Additional comments (4)
sebs/experiments/invocation_overhead.py (4)
148-148: Updated method signature to include required benchmark parameter.The
enforce_cold_startmethod now correctly includes the benchmark parameter, which aligns with the interface changes in the deployment clients. Based on the provided code snippets from various cloud provider implementations (AWS, Azure, GCP), this parameter is now required to properly enforce cold starts.
171-171: Parameter added but not used in method body.The
extend_time_intervalparameter has been added to align with other experiment classes (like NetworkPingPong), but it's not being used anywhere in the method implementation. Consider either documenting its purpose or implementing its functionality.Is this parameter intended for future use or should it be implemented in this method? Please check if there are similar implementations in other experiment classes that might provide guidance on how to use this parameter.
226-226: Fixed CSV processing by skipping header row.Good addition - this correctly skips the header row of the CSV file, preventing it from being processed as data which would cause incorrect results.
281-281: Updated path to access timestamp in response structure.The path to access the timestamp has been updated from
res.output["result"]["result"]["timestamp"]tores.output["result"]["output"]["timestamp"]to reflect changes in the response data structure.

Method signature updated for standardization
The process method signature has been updated to include additional parameters (sebs_client, deployment_client, logging_filename, extend_time_interval), aligning with other experiment implementations. However, these new parameters are not utilized within the method body.
Add type annotations to the new parameters and consider implementing functionality that uses these parameters or document why they're not needed:
- def process(self, sebs_client, deployment_client, directory, logging_filename, extend_time_interval):
+ def process(
+ self,
+ sebs_client: "SeBS",
+ deployment_client: FaaSSystem,
+ directory: str,
+ logging_filename: str,
+ extend_time_interval: int
+ ):
+ """Process experiment results.
+
+ Args:
+ sebs_client: The SeBS client instance
+ deployment_client: The deployment client instance
+ directory: Directory containing experiment results
+ logging_filename: Name of the logging file
+ extend_time_interval: Time interval extension in minutes
+ """Check whether the extend_time_interval parameter is used similarly in other experiment classes:
🏁 Script executed:
#!/bin/bash
# Check how extend_time_interval is used in other experiment classes
rg -A 10 "extend_time_interval" --type pyLength of output: 4376
Action Required: Enhance the Method Signature in network_ping_pong.py
The process method now includes additional parameters for consistency with other experiments, but these parameters—particularly extend_time_interval—aren't utilized in the method body. In other experiment classes (e.g., perf_cost.py and invocation_overhead.py), extend_time_interval adjusts metric retrieval timing. To maintain clarity and consistency, please update the method signature in sebs/experiments/network_ping_pong.py as follows:
- Add type annotations for all parameters.
- Include a docstring that explains the purpose of each parameter.
- Document or implement the usage of
extend_time_interval. If it is intentionally unused in this experiment, add a comment in the docstring to clarify why.
Below is a suggested diff:
- def process(self, sebs_client, deployment_client, directory, logging_filename, extend_time_interval):
+ def process(
+ self,
+ sebs_client: "SeBS",
+ deployment_client: FaaSSystem,

+ extend_time_interval: Time interval extension in minutes.
+ Note: This parameter is used in other experiments to adjust metric collection timing.
