# Day 13: Monitor and Log with Google Cloud Operations Suite: Challenge Lab
## Tasks:
1. Initialize Cloud Monitoring.
**Navigation menu > Monitoring**
PS: 這步造理說滿簡單的，但第一次第二次做時，Not work!
後來隔一段時間再做沒有特別更動操作就可以了，估計是平台(Qwiklabs)的Checkpoints問題
2. Configure a Compute Instance to generate Custom Cloud Monitoring metrics
**Navigation Menu > Compute Engine > VM Instances**
- 點選`video-queue-monitor`的 instance
- 點選**Edit**
- 找到**Custom metadata**
設定MY_PROJECT_ID
設定INSTANCE-ID(往上滑頁面有INSTANCE-ID可複製)
設定MY_GCE_INSTANCE_ZONE="us-east1-b"
PS: 不確定Zone設別的有沒有差
- **Save**
- Stop and Start `video-queue-monitor`
PS: 可以Check `右上`提醒紀錄點開看狀態切換
3. Create a custom metric using Cloud Operations logging events
**Navigation menu > Logging > Logs Explorer**
- 在Query Section 填寫

        textPayload=~"file_format\: ([4,8]K).*"

接著**Run Query**
- 右下有 **Action**,點Action再下拉點**Create Metric**
- custom metric的name設定為`large_video_upload_rate`

4: Add custom metrics to the Media Dashboard in Cloud Operations Monitoring
**Navigation menu > Monitoring > Dashboards**
- click **Media_Dashboard**

5: Create a Cloud Operations alert based on the rate of high resolution video file uploads
**Navigation menu > Monitoring > Alerting**
