Monitoring Rules: Best practices for setting up alerts
December 18, 2018
CloudRadar is preconfigured with Smart Alerts based on best practices for monitoring of your servers, networks or websites. This is a set of standard rules that are activated the moment you switch on your CloudRadar monitoring, ensuring that you are covered immediately.
Of course, we realise that every organisation has unique circumstances and needs, and that monitoring software should be adaptable to these needs.
CloudRadar allows you to set up, change or remove alerting rules as often as you like - customise rules and rule triggers according to your unique environment and requirements, then change it as often as you need.
This is how to do exactly that:
What is a Monitoring Rule?
A rule in CloudRadar contains a set of Conditions and an Action:
- Using the Conditions, you specify when the results of particular host check should trigger an Action, for example when Disk Fill levels are over 95%.
- By setting the Action you specify what should happen when the Conditions are met - for example, raising an alert and sending it to a specific email address.
How does it work?
- You can define as many Rules and Checks for your Hosts as you need.
- Every time the results from a Host Check are available (for example every 60sec, 90sec etc), CloudRadar starts an internal process for each Rule that applies to this Check.
- The process evaluates the data from the Check based on the Rule Conditions, then takes the specified Action.
Adding a Rule
- Choose “Rules” on the left, then choose the “Add Rule” button in the top right part of the screen.
- In the AND AFFECTED HOST field, set the hosts for which the rule should be applied:
- Choose “Is an” to apply the rule to all hosts
- Choose “Is” to select one of your hosts, or .
- You can also specify hosts by name, FQDN/IP, or tag by entering a corresponding string (the * wildcard is allowed).
- In the “and check type is” field, set whether the rule should be applied for Any, Service Checks, Web Site checks, or Agent.
- Choosing Service Check or Website Check will open an additional “and check is” field, where you should select one of the available check types. You can choose between evaluating the success of single checks, or evaluating the success (measuring the performance) of several consecutive checks.
- In the “and check” field, you choose what the Condition is that will trigger the Action.
- In the “do” field, select the Action CloudRadar should take when all of the Conditions you have set in the rule are met.
- You can choose between raising an alert, raising a warning, or ignoring the failed checks.
- Set the processing mode of the rule:
- Select “Active” when the rule should be processed by CloudRadar.
- Click on “ADD RULE” to save your new rule.
The available rules are listed on the Rules page, which you can access from the left-hand menu.
You can modify a rule using the buttons/icons in the right part of the page. Click on the line of three grey dots next to the rule you want to modify:
- Edit: open the rule to modify its Conditions or Action (the red pencil icon)
- Delete: remove the selected rule.
- Sort: Move the selected alert up or down with the arrows that appear.
That is it – your comprehensive easy-to-follow guide to set alerts for all your critical metrics!
