op-monitorism/eventer/monitor.go (2)
23-24: Encapsulate thecountervariable within theMonitorstruct.Using a global variable for
countercan lead to issues in concurrent environments. Consider movingcounterinto theMonitorstruct to manage state more effectively.Modify the struct and initialization:
type Monitor struct { log log.Logger // ... other fields + counter int } // In the constructor: return &Monitor{ log: log, l1Client: l1Client, // ... other fields + counter: 0, }
181-184: Implement retry logic for failed RPC calls.When RPC calls fail, adding a retry mechanism can improve resilience against transient issues.
Consider using an exponential backoff strategy:
import "github.com/cenkalti/backoff/v4" // Replace direct calls with retry logic operation := func() error { header, err := m.l1Client.HeaderByNumber(context.Background(), nil) if err != nil { m.unexpectedRpcErrors.WithLabelValues("L1", "HeaderByNumber").Inc() m.log.Warn("Failed to retrieve latest block header", "error", err.Error()) return err } // ... rest of the logic return nil } backoffConfig := backoff.NewExponentialBackOff() backoffConfig.MaxElapsedTime = 1 * time.Minute err := backoff.Retry(operation, backoffConfig) if err != nil { m.log.Error("Failed to retrieve block header after retries", "error", err) return }Also applies to: 196-199

48-48: Update environment variable names to accurately reflect their purpose.The comments indicate a need to change
NICKNAMEandPATH_YAMLto more descriptive names likeBLOCKCHAIN_NAME. This can improve clarity and maintainability.Update the environment variables:
&cli.StringFlag{ Name: NicknameFlagName, Usage: "Nickname of chain being monitored", - EnvVars: opservice.PrefixEnvVar(envVar, "NICKNAME"), //need to change the name to BLOCKCHAIN_NAME + EnvVars: opservice.PrefixEnvVar(envVar, "BLOCKCHAIN_NAME"), Required: true, }, &cli.StringFlag{ Name: PathYamlRulesFlagName, Usage: "Path to the yaml file containing the events to monitor", - EnvVars: opservice.PrefixEnvVar(envVar, "PATH_YAML"), //need to change the name to BLOCKCHAIN_NAME + EnvVars: opservice.PrefixEnvVar(envVar, "YAML_RULES_PATH"), Required: true, },Also applies to: 54-54

3-3: Enhance the introduction with specific driver examples.Consider listing the specific database drivers that are currently supported to help users understand their options immediately.
-op-eventer is a customizable monitoring tool that listens to a set of events configured via a YAML file. It includes a set of listeners that respond to these events and perform specific actions. The events produced are written into a customizable database, which can be a file, a database, Prometheus, etc., depending on the driver used. The final output can also be written based on the driver used. +op-eventer is a customizable monitoring tool that listens to a set of events configured via a YAML file. It includes a set of listeners that respond to these events and perform specific actions. The events produced are written into a customizable database using supported drivers such as SQLite, PostgreSQL, or Prometheus. The final output format adapts based on the selected driver.
28-40: Add environment variable usage examples.The CLI options section would benefit from examples showing how to use environment variables, especially for common configurations.
Add this section after the OPTIONS:
Example using environment variables: ```bash export GLOBAL_EVENT_MON_L1_NODE_URL="https://mainnet.infura.io/v3/YOUR-PROJECT-ID" export GLOBAL_EVENT_MON_NICKNAME="mainnet" export MONITORISM_METRICS_ENABLED=true--- `65-68`: **Enhance execution instructions with prerequisites and validation steps.** The execution example would benefit from: 1. Prerequisites (required directory structure) 2. Validation steps to verify successful setup 3. Expected output examples Add these sections before the execution command: ```markdown ### Prerequisites 1. Ensure the rules directory exists: `mkdir -p /tmp/Monitorism/op-monitorism/global_events/rules/rules_mainnet_L1` 2. Copy the template YAML file to the rules directory ### Validation After starting the monitor, verify: 1. Metrics endpoint is accessible (if enabled): `curl http://localhost:7300/metrics` 2. Events are being logged according to your configuration

🛠️ Refactor suggestion
Avoid using panic in library functions; return errors instead.
Using panic for error handling in ReadYamlFile is not recommended. It's better to return the error and let the caller handle it appropriately.
You can modify the function to return an error:
-func ReadYamlFile(filename string) Configuration {
+func ReadYamlFile(filename string) (Configuration, error) {
var config Configuration
data, err := os.ReadFile(filename)
if err != nil {
- fmt.Println("Error reading YAML file:", err)

🛠️ Refactor suggestion
Replace panic with proper error handling in ReadAllYamlRules.
In ReadAllYamlRules, using panic can cause unexpected crashes. Instead, return errors to the caller to handle them gracefully.
Modify the error handling as follows:

+func ReadAllYamlRules(PathYamlRules string, log log.Logger) (GlobalConfiguration, error) {
var GlobalConfig GlobalConfiguration

🛠️ Refactor suggestion
Handle invalid signatures without panicking.
In FormatAndHash, panicking on an invalid signature can cause the entire application to crash. It's better to return an error to handle this scenario gracefully.
Modify the function to return an error:

🛠️ Refactor suggestion
Avoid using time.Sleep in production code.
Pausing execution with time.Sleep(10 * time.Second) can hinder performance. If the delay is necessary for startup initialization, consider implementing a more robust synchronization mechanism or using a configuration setting.
If this is for debugging, you might want to conditionally execute it:

💡 Codebase verification
Incorrect configuration: Mainnet addresses used in Sepolia environment
The contract address and authorized pause address are specifically designated for mainnet use:
0xbEb5Fc579115071764c7423A4f12eDde41f106Edis the Optimism Portal contract for mainnet0x9BA6e03D8B90dE867373Db8cF1A58d2F7F006b3Ais a mainnet-specific safe address
Sepolia should use its own network-specific addresses, as evidenced by different safe addresses in the codebase (e.g., Sepolia safe: 0x837DE453AD5F21E89771e3c06239d8236c0EFd5E).

Verify contract and authorized addresses for each environment.
The same contract address and authorized pause addresses are used for both Mainnet and Sepolia. This might not be intentional and could pose a security risk.

op-eventer/setup/query_exec.py (3)
25-31: Handle potential query failures gracefully.
The current approach doesn't capture exceptions from the BigQuery client. If a query or job fails, the script will terminate abruptly. Consider wrapping this logic in a try-except block and logging any failures for more robust error handling.
67-73: Consider batching or conditional alerting for large result sets.
Sending an alert per row could lead to high alert volumes. If the data set is large, it may overwhelm the metrics system. Consider adding batching logic or thresholds for triggering alerts.
82-90: Infinite loop may benefit from scheduling.
An infinitewhile Trueloop with a fixed sleep might be better replaced or supplemented by cron-like scheduling, or at least a break condition, to prevent indefinite running in certain environments.op-eventer/setup/consumers/metrics.sh (2)
6-9: Quoting arguments in log function.
When using$*, unusual spacing or special characters could break log messages. Consider quoting arguments to preserve formatting.-function log { - echo $(date "+%Y-%m-%d %H:%M:%S") $* +function log { + echo "$(date "+%Y-%m-%d %H:%M:%S")" "$@" }
25-30: Validate expected script arguments.
The script assumes three arguments are always passed in. If arguments are missing, the script silently fails. Add a quick usage check to improve reliability.op-eventer/setup/run.sh (1)
25-25: Validate monitoring configuration existence.
Before invokingmonitoring.yaml, consider verifying that this file actually exists and is valid. If the file is missing or malformed, the script will exit without a clear error message.op-eventer/monitoring/monitoring.yaml (1)
13-24: Optimize BigQuery performance and add time-based filtering.The query could benefit from several optimizations:
- Add block timestamp/number filtering to limit the data scanned
- Handle potential null values in

3-9: Verify contract addresses and authorized pause addresses across networks.A few concerns about the configuration:
- The contract address is identical for both networks (
0xbEb5Fc579115071764c7423A4f12eDde41f106Ed). This is unusual as contracts typically have different addresses on different networks.- The authorized addresses are very similar (
...b3bvs...b3a), which could indicate a potential typo.✅ Verification successful
Configuration is correct and follows expected patterns
The identical contract address (
0xbEb5Fc579115071764c7423A4f12eDde41f106Ed) across networks is correct as it's the Optimism Portal contract. The different authorized pause addresses for Mainnet (...b3b) and Sepolia (...b3a) follow security best practices by using network-specific addresses.🏁 Scripts executed

Using the same contract address across networks is intentional ✅
The contract is part of a monitoring system that tracks pause events, with properly configured network-specific settings and different priority levels (P1 for Mainnet, P2 for Sepolia).

🛠️ Refactor suggestion
Add error handling for BigQuery client initialization and query execution.
The function should handle potential errors when initializing the client and executing queries.

- client = bigquery.Client()
+ try:
+ client = bigquery.Client()
+ except Exception as e:
+ print(f"Failed to initialize BigQuery client: {e}")

Add error handling for the main loop.
The infinite loop should handle exceptions and implement proper backoff strategy.

4-5: Add error handling between diff and sync operations.While it's good practice to run diff before sync, we should ensure the diff operation succeeds before proceeding with sync.

4-7: Consider using more robust path handling.While the current path construction works, it could be made more robust:
- Quote the paths to handle spaces
- Use
readlink -ffor true absolute paths-SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" +SCRIPT_DIR="$( cd "$( dirname "$(readlink -f "${BASH_SOURCE[0]}")" )" && pwd )" -VENV_DIR="$SCRIPT_DIR/../../.venv" +VENV_DIR="${SCRIPT_DIR}/../../.venv" -MONITORING_DIR="$SCRIPT_DIR/../monitoring" +MONITORING_DIR="${SCRIPT_DIR}/../monitoring"op-eventer/setup/alerts/op-eventer.yaml (1)
6-9: Enhance alert annotations with detailed descriptions.The current annotations are generic. Consider adding:
- Specific impact description
- Recommended actions
- Link to runbook

13-24: Optimize BigQuery query performance.Consider these optimizations:
- Add date range filter to reduce scanned data
- Use partitioned tables if available
- Consider materializing frequently accessed data

The hardcoded path ~/alerts_cred.env could cause issues in different environments.
