### Describe Collector Pod for Last State Information

Source: https://github.com/stackrox/collector/blob/master/docs/troubleshooting.md

Command to describe a Collector pod, focusing on its last terminated state. This helps in identifying the reason for a crash, such as specific error messages or exit codes.

```shell
# substitute your collector pod into this command
$ kubectl describe pod -n stackrox collector-vclg5
[...]
    Last State:     Terminated
      Reason:       Error
      Message:      No suitable kernel object downloaded
      Exit Code:    1
      Started:      Fri, 21 Oct 2022 11:50:56 +0100
      Finished:     Fri, 21 Oct 2022 11:51:25 +0100
[...]
```

--------------------------------

### Checkout and Pull Master Branch (Shell)

Source: https://github.com/stackrox/collector/blob/master/docs/release.md

Ensures the local repository is on the master branch and up-to-date with the remote repository. This is a prerequisite for manual release processes.

```shell
git checkout master
git pull
```

--------------------------------

### Tag and Push Release Version (Shell)

Source: https://github.com/stackrox/collector/blob/master/docs/release.md

Tags the current commit with the specified release version (e.g., '3.22.0') and pushes the tag to the origin repository. This marks the official release point.

```shell
git tag "${COLLECTOR_RELEASE}.${COLLECTOR_PATCH_NUMBER}"
git push origin "${COLLECTOR_RELEASE}.${COLLECTOR_PATCH_NUMBER}"
```

--------------------------------

### View Collector Logs (Kubernetes Bash)

Source: https://context7.com/stackrox/collector/llms.txt

Commands to view logs for the StackRox collector pods in Kubernetes. This includes fetching the collector pod name, viewing current logs, retrieving logs from a previous container instance (after a crash), and describing the pod for termination messages.

```bash
# Get collector pod name
kubectl get pods -n stackrox -l app=collector
# Output: collector-vclg5   1/2   Running   0   2m41s

# View current logs
kubectl logs -n stackrox collector-vclg5 collector

# View previous container logs (after crash)
kubectl logs -n stackrox collector-vclg5 collector --previous

# Check pod status for termination message
kubectl describe pod -n stackrox collector-vclg5
# Look for:
#   Last State:     Terminated
#   Message:      No suitable kernel object downloaded
```

--------------------------------

### Control CPU Profiling and Download Profiles (curl)

Source: https://context7.com/stackrox/collector/llms.txt

Commands to interact with the collector's CPU profiling endpoint. This allows stopping profiling, downloading the profile data, and then analyzing it using the pprof tool. Ensure you have debugging symbols for accurate analysis.

```bash
curl -X POST -d "off" http://collector:8080/profile/cpu

curl http://collector:8080/profile/cpu > cpu.prof

pprof --text ./collector heap.prof
```

--------------------------------

### Update and Tag Falcosecurity-libs Submodule (Shell)

Source: https://github.com/stackrox/collector/blob/master/docs/release.md

Updates the falcosecurity-libs submodule, tags it with the current release version, and pushes the tag. This ensures the collector uses the correct version of its dependencies.

```shell
git submodule update --init falcosecurity-libs
cd falcosecurity-libs
git tag "${COLLECTOR_RELEASE}.${COLLECTOR_PATCH_NUMBER}"
git push origin "${COLLECTOR_RELEASE}.${COLLECTOR_PATCH_NUMBER}"
```

--------------------------------

### Collector Runtime Configuration YAML

Source: https://context7.com/stackrox/collector/llms.txt

Dynamically configure the collector using a YAML file, which can be updated without restarting the collector. This supports settings for networking features like external IPs and connection limits.

```yaml
# /etc/stackrox/runtime_config.yaml (or ConfigMap)
networking:
  externalIps:
    enabled: ENABLED           # ENABLED or DISABLED
    direction: BOTH            # INGRESS, EGRESS, or BOTH
  maxConnectionsPerMinute: 2048
```

```yaml
# Kubernetes ConfigMap example
apiVersion: v1
kind: ConfigMap
metadata:
  name: collector-config
  namespace: stackrox
data:
  runtime_config.yaml: |
    networking:
      externalIps:
        enabled: ENABLED
        direction: EGRESS
      maxConnectionsPerMinute: 1234
