Setup and configuration

  • Adding Google Cloud Load Balancing while configuring a new Google Cloud monitor

    If you have not configured a Google Cloud monitor yet, add one by following the steps below:

    1. Log in to your Site24x7 account.
    2. Go to Cloud > GCP > Add GCP Monitor or Admin > Cloud Monitoring > Google Cloud Platform(GCP).
    3. Provide a unique display name for identification purposes.
    4. Upload a service account JSON file to authenticate Site24x7 for performing resource discovery.
    5. Select Cloud Load Balancing from the Select the Resources for Monitoring list.
    6. Select existing Notification Profiles, User Alerts Groups, Tags, and IT Automation Templates or add new ones. You can also integrate Site24x7's alarms with your preferred third-party service.
    7. Click Start GCP Monitoring.
  • Adding Google Cloud Load Balancing to an existing Google Cloud monitor

    If you already have a Google Cloud monitor configured for the service account, you can add Cloud Load Balancing by following the steps below:

    1. Log in to your Site24x7 account.
    2. Go to Cloud > GCP and select your GCP monitor.
    3. Click the hamburger Hamburger icon icon next to Service View and select Edit, which brings you to the Edit GCP Monitor page.
    4. On the Edit GCP Monitor page, select Cloud Load Balancing from the Select the Resources for Monitoring list and click Save.
    5. After successful configuration, go to Cloud > GCP > Cloud Load Balancing. Now you can view the discovered Cloud Load Balancing resources.
It will take approximately five minutes to discover new GCP resources.

Polling frequency

Site24x7's Cloud Load Balancing monitor collects the metrics data every five minutes and the statuses of your Cloud Load Balancing resources every minute.

Supported metrics

Metric name Description Statistic Unit
Backend Request Bytes The number of bytes sent as requests from external HTTP(S) load balancer to the backends Total Bytes
Backend Request Count The number of requests served by the backends of the external HTTP(S) load balancer Total Count
Backend Response Bytes The number of bytes sent as responses from the backends (or cache) to the external HTTP(S) load balancer Total Bytes
Backend Latency A distribution of the latency calculated from when the request was sent by the proxy to the backend until the proxy received from the backend Average Milliseconds
Closed Connections The total number of connections that were terminated over the TCP proxy or SSL proxy load balancer Total Count
Egress Bytes The total number of bytes sent from the VM to the client using proxy Total Bytes
Egress Packets The total number of packets sent from the backend of the external network load balancer to the client Total Count
Frontend RTT A distribution of the smoothed RTT measured by the proxy's TCP stack, each minute application layer bytes pass from proxy to client Average Milliseconds
Ingress Bytes The total number of bytes sent from the client to the VM using proxy Total Bytes
Ingress Packets The number of packets sent from the client to the backend of the external network load balancer Total Count
New Connections Opened The total number of connections that were created over TCP proxy or SSL proxy load balancer Total Count
Open Connections The total current number of outstanding connections through the TCP proxy or SSL proxy load balancer Total Count
RTT Latencies A distribution of the round trip time latency, measured over TCP connections for the external network load balancer Average Milliseconds
Request Bytes The number of bytes sent as requests from clients to external HTTP(S) load balancer Total Bytes
Request Count The number of requests served by the external HTTP(S) load balancer Total Count
Response Bytes The number of bytes sent as responses from the external HTTP(S) load balancer to the clients Total Bytes
Total Latency A distribution of the latency calculated from when the request was received by the external HTTP(S) load balancer proxy until the proxy got acknowledged from the client on last response byte Average Milliseconds

Threshold configuration

  • Global configuration
    1. In the Site24x7 web client, go to the Admin section on the left navigation pane.
    2. Select Configuration Profiles from the left pane and select Threshold and Availability from the drop-down menu.
    3. Click Add Threshold Profile in the top-right corner.
    4. For Monitor Type, select Cloud Load Balancing.
    5. Now you can set the threshold values for the metrics listed above.
  • Monitor-level configuration
    1. In the Site24x7 web client, go to Cloud > GCP > Cloud Load Balancing.
    2. Select a resource you would like to set a threshold for, then click the hamburger Hamburger icon icon.
    3. Select Edit, which directs you to the Edit Cloud Load Balancing Monitor page.
    4. You can set the threshold values for the metrics with the Threshold and Availability option.
    5. You can also configure IT Automation at the attribute level.

IT Automation

By leveraging Site24x7's IT Automation tools, you can automate repetitive tasks, respond quickly to performance issues, and minimize downtime or disruptions. The alarm engine in Site24x7 continually evaluates system events based on the thresholds you have set. When a breach occurs, the mapped automation associated with that event is triggered, ensuring prompt remediation and minimizing the impact on your IT infrastructure.

How to configure IT Automation for a monitor

Configuration Rules

Site24x7's Configuration Rules feature lets you edit multiple monitors and streamline the configuration process for your monitoring resources. With Configuration Rules, you can easily associate different monitor groups or add specific tags to multiple monitors simultaneously. This eliminates the need to manually edit each monitor individually, saving you valuable time and effort.

How to add Configuration Rules

Summary

The Summary tab will give you the performance data organized by time for the metrics listed above. To view the summary:

  1. Go to Cloud > GCP > Cloud Load Balancing.
  2. Select a resource.
  3. Click the Summary tab.

Configuration Details

The Configuration Details tab provides details on the configurations of application instances. To get the configuration details:

  1. Go to Cloud > GCP > Cloud Load Balancing.
  2. Select a resource.
