E2E CloudEvent Monitoring FAQ
For help with a message in MyAccount, or with alert emails or WhatsApp alerts that do not arrive, see Troubleshooting Event Monitoring.
What Event Monitoring covers
Section titled “What Event Monitoring covers”Which resources can Event Monitoring watch?
Section titled “Which resources can Event Monitoring watch?”Nodes, load balancers, DBaaS instances, and the nodes of Kubernetes clusters. Each service has its own list of triggers. A node offers Processor Load, Consumed Memory, Free Disk Space, Volume Read Ops, and Volume Write Ops. A DBaaS instance has its own, such as Slow Query Rate and Query per second. See Create an alert.
Is Event Monitoring charged?
Section titled “Is Event Monitoring charged?”No. Alerts, alert groups, and the Monitoring Dashboard are free.
Are my alerts the same in Delhi and Chennai?
Section titled “Are my alerts the same in Delhi and Chennai?”No. Alerts, alert groups, and dashboard problems belong to one project and one region. Event Monitoring shows those of the project and region selected in MyAccount, so switch the region to see the other region’s alerts. An alert chooses its alert groups from its own project. See Event Monitoring.
Alerts
Section titled “Alerts”Where do I see the alerts I have set?
Section titled “Where do I see the alerts I have set?”On Manage Alerts. Open Event Monitoring in the side menu, then click Manage Alerts on the Monitoring Dashboard. The dashboard itself lists problems, the alert conditions currently open on your resources. See Alerts and problems.
Can one alert watch several resources?
Section titled “Can one alert watch several resources?”Yes. One alert can cover several running resources of one service, and All picks every one of them. It stays one row on Manage Alerts. To watch two services, such as nodes and load balancers, create an alert for each. See Create an alert.
How does a Processor Load threshold work?
Section titled “How does a Processor Load threshold work?”The threshold is a percentage of the resource’s vCPUs. The alert fires when the five-minute load average stays above that share of the vCPU count for five minutes. On a node with four vCPUs, a threshold of 80% means a load average of 3.2. A DBaaS instance’s CPU Load Average works the same way on the one-minute load average. See Create an alert.
How do I get an alert when a disk is nearly full?
Section titled “How do I get an alert when a disk is nearly full?”Create a Free Disk Space alert with Less than as the operator. The alert compares the share of the disk that is free. A threshold of 10 fires when less than 10% of the disk is free. With one node selected, the Volume field also offers its attached volumes. Before you choose an attached volume, mount it on the node and turn on its monitoring. See Create an alert.
What does severity change?
Section titled “What does severity change?”Severity is the label the problem carries, from Not classified through Information, Warning, Average, and High to Disaster. The trigger, operator, and threshold alone decide when the alert fires. A new alert starts at High. The Monitoring Dashboard counts problems by severity. The Monitoring Alerts card on the MyAccount dashboard shows High and Disaster as HIGH, Average as MEDIUM, and Information and Warning as LOW. See Read the monitoring dashboard.
Where do I create a Webcheck alert?
Section titled “Where do I create a Webcheck alert?”On a node’s own Alerts tab, the only alert form that offers Webcheck. A Webcheck fires when the address you give does not answer with HTTP status 200. It also fires when the page does not contain the text you expect. A node can have up to five Webcheck alerts. See Set up alerts on a node.
Why do my resources have alerts I never created?
Section titled “Why do my resources have alerts I never created?”E2E adds default alerts when monitoring is set up on a new node, load balancer, DBaaS instance, or Kubernetes node. They notify the project’s default alert group, which starts with the account owner as its only member. They are listed on Manage Alerts next to your own, so you can edit, pause, or delete them there. To send the default alerts to others as well, edit those alerts and add your own alert group under Alert Group(s). Alerts created on a resource’s own Alerts tab are listed on Manage Alerts too. A DBaaS instance comes with a helper machine whose name ends in -maxscale. The helper machine’s default alerts are listed on Manage Alerts as node alerts, though it is not in your nodes list. See Alerts and problems.
What happens to an alert when I delete a node?
Section titled “What happens to an alert when I delete a node?”The node is removed from the alert, and the alert keeps watching any other resources it covers. The same happens when you delete a load balancer. An alert left with no resources disappears from Manage Alerts. See Edit, pause, or delete an alert.
Does pausing an alert stop the check?
Section titled “Does pausing an alert stop the check?”No. Pausing stops the alert’s notifications until you resume it, and the check goes on. See Edit, pause, or delete an alert.
Do I get a notification when a problem clears?
Section titled “Do I get a notification when a problem clears?”No. Each problem sends one notification, when it starts. To see which problems are still open, check the Monitoring Dashboard. See Read the monitoring dashboard.
Alert groups and notifications
Section titled “Alert groups and notifications”Who receives an alert?
Section titled “Who receives an alert?”Every member of each alert group linked to the alert. Each member gets an email at the address they sign in to MyAccount with. See Manage alert groups.
Can I get alerts on WhatsApp?
Section titled “Can I get alerts on WhatsApp?”Yes, on the account owner’s phone number, for every alert that notifies a group the owner belongs to. One switch in General Settings turns it on for the whole account, and email goes out either way. See How alerts reach people.
Are alert groups the same as IAM user groups?
Section titled “Are alert groups the same as IAM user groups?”No. An alert group is a named list of MyAccount users that alerts notify. You make one under Manage Alert Groups or from any alert form, and you change and delete it under Manage Alert Groups. IAM’s user groups grant access to resources and live in a separate list. See Alert groups.
Can I add an email address that is not a MyAccount user?
Section titled “Can I add an email address that is not a MyAccount user?”No. To send notifications to someone new, invite them to your account and the project. Once they have accepted their invitation, add them to the group. For who can be added, see Manage alert groups.
The Monitoring Dashboard
Section titled “The Monitoring Dashboard”How far back can I look on the dashboard?
Section titled “How far back can I look on the dashboard?”Up to 30 days, with the 30 Days period or a Custom range. See Read the monitoring dashboard.
Which port does monitoring use on my node?
Section titled “Which port does monitoring use on my node?”Port 10050. E2E’s monitoring server connects to the node’s first private IP address on that port, and a node it cannot reach has blank graphs. See Troubleshooting node monitoring and encryption.
