Server Performance Monitoring and Alerts

Alert policies are user-created rules to receive notifications or invoke actions when there is any metric change to the underlying infrastructure. The alerting system works by sending automatic response notifications to a user-defined email list when the value of the metric relative to a preset threshold level changes.

Introduction

E2E Networks Server Health Monitoring provides visibility into real-time monitoring of metrics collected from your virtual machine Nodes and resource usage across your infrastructure. The Server Health Monitoring providers infrastructure insights with graphs and usage statistics. You can easily configure alert policies, notifications and respond quickly to the critical situations where server health may be affected, or resource threshold is reached to the maximum limit. Overall it helps in planning and proactively averts future problems.

In this guide, we’ll provide an overview of E2E Network’s Server Health Monitoring and discuss how it can help you to better manage your infrastructure resources.

Once you are into E2E Networks ‘My Account’ dashboard, select ‘Server Health’ under the services tab on the left side of your dashboard.

Server Health Monitoring

Server Health is a free service that provides insights into resource usage across your infrastructure. There are several different components which display metrics to help you track the operational health of your infrastructure.

Select the node for which you want to check the metrics

General Information

Check the server information such as the current status and the overall uptime.

CPU Performance

Check your CPU vitals such as load average over a pre-set refresh time interval and the current overall CPU usage.

Disk Space

Monitor the overall used & free space on your compute node disk.

Memory Usage

Monitor the overall used & free RAM on your compute node.

Network Traffic Statistics

View your network stats such as incoming & outgoing traffic of your private IP(eth0) & Public IP(eth1)

 

Server Health Alerting

Alert policies are user-created rules to receive notifications or invoke actions when there is any metric change to the underlying infrastructure. The alerting system works by sending automatic response notifications to a user-defined email list when the value of the metric relative to a preset threshold level changes.

Server Health Alerts gives you the ability to create triggers about your server’s performance and resource utilization metrics which timely notifies you about any subsequent behavior changes.

Select Node

To Setup Alerts select the node from the dropdown list for which you want to set the trigger & click on ‘Add New Alert’.

Define Trigger Parameters

These are the rules which can be set to trigger events. The defined actions will be validated and if the condition meets then an alert event is triggered.

  • CPU Load Average – Set the CPU load threshold level which can be greater than, less than or equal, not equal to a threshold defined value
  • Percentage Free Memory – Set the memory utilization level which can be greater than, less than, equal or not equal to a threshold defined value
  • Percentage Free Disk Space – Set the disk space utilization level which can be greater than, less than, equal or not equal to a threshold defined value
  • Webcheck – Webcheck is a web URL monitoring tool which will create an alert on 2 conditions.
    • Success code 200 – The request was fulfilled.
    • Text match – Webcheck program crawls on a given website URL and checks specific phrases of text on the website. If webcheck finds any changes different from the standard text then you will receive an email notification.

Max Webcheck Limit – 5 URL’s

Once you have defined the pre-sets then click on ‘Add’ button to finally add the alert conditions.

Alert Contacts

The predefined contacts will receive email notifications based on the triggers.

Click on the configure tab to input the email addresses on which you want to send the notification alerts.

Enter the list of email addresses on which you want to send alerts.

Note – You can use these delimiters  – comma (,) or Tab or Semi-colon (;) or New Line to separate multiple emails in a list

Click on ‘Save’ button to save the list.

In case an alert condition is met then the emails entered will receive notification. You can easily manage the Emails on which you want to send the alerts by simply adding or deleting them from the list.
