ManageEngine® Applications Manager Chapter 7.8 Configuring Dependencies and Alarm Rules |
||
Dependencies: They determine the health/availability of a Monitors. They consist of the dependent parameters of the Monitor based on which the severity of the health and availability are determined. More
Alarm Rules: They determine the health/availability of a Monitors Groups. More
Dependent Devices: You can configure a dependent device in such a manner that if the availability of the dependent device is down, all the Monitors/Monitor Group's availability under the dependent device will be down. Also, you have the option of supressing all the alarms caused by the dependent device.
Configuring Dependencies for Monitors:
By configuring dependencies, you can specify whether the health or availability depends on all or few dependencies. The severity is also determined by order of severity which is given below:
Critical
Warning
Clear
For example, If there are 9 dependencies in a Monitor Group where three are critical, three are warning, and three are clear and the severity of Health of Monitor Group is based on any three selected dependencies, then the severity will be Critical as per the order of severity.
Select the Home tab that lists all the Monitor Groups.
Click on the Monitor Group that lists the Monitor.
Click on the Configure
Alarm icon of the respective Monitor. This opens
the Configure Alarm screen.
Choose Health or Availability from the combo box. The dependent attributes will be shown in the list box under dependencies.
Select and move the required attributes from the left box to the right box using >> button. By default, all the dependencies for the attributes of the monitors are added in the right box. You can also remove the default settings using the Action / Alarm Settings option.
Specify whether the rule
for determining the severity for health or availability.
Depends on all selected parameters: The severity of health depends
on the severity of all the selected parameters.
Depends on any "n" selected parameters: The severity
of health depends on only 'n' selected parameters. The number of parameter,
n has to be selected from the
combo box.
Click Save All to complete configuring dependencies.
Configuring Alarm Rules for Monitor Groups:
By configuring Alarm Rules, you can specify how the health or availability depends on the constituent Monitors in that Monitor Group. For eg., using Alarm Rules, you can say Health of the Monitor Group is Critical if the health of any two monitors in the monitor group is critical or Availability of the Monitor Group is Critical if health of any one of the monitors is critical.
To configure alarm rules for the Monitor Group, do the following steps:
Select the Home tab that lists all the Monitor Groups.
Click on the Monitor Group you want to configure alarm rules.
Click on the Configure
Alarm icon of the Monitor Group [under Today's Availability]. This opens
the Configure Alarm screen.
Select the status you wish to alarm on. Choose Health or Availability from the combo box.
For Availability Alarm Rule, set the rule as -
Monitor Group is down if any/all/selected Monitor's availability is down
or
Monitor Group is down if Monitor's health is critical/warning
For Health Alarm Rule, set the rule as -
Monitor Group is Critical if any/all/selected Monitor's availability is down
or
if Monitor's health is critical/warning
Monitor Group is Warning if
any/all/selected Monitor's availability is down
or
if Monitor's health is critical/warning
You have the option of setting any number of rules. For eg., it can be Monitor Group's Availability is down if any one of the monitor's availability is down or if the health of any one of the monitor is critical. Likewise, you can have your customized set of Alarm Rules.
Note: In Alarm Rules
1. Rule processing order will be Down,Critical and Warning i.e., Applications Manager will first process Down rules followed by Critical and Warning.
2. Processing rules will be stopped at any condition if rules is matched, further it won't proceed to process rules.
3. In 'Selected' rule type, Monitor Group status will depend on all the selected monitors severity.
Configuring Dependent Device
To configure dependent device for the Monitor Group, do the following steps:
Select the Alarms tab. It opens up the Alarm dashboard.
Click on the Configure Alarms link, found under the list of monitors with critical alerts. It opens up the Global alarm configuration page.
Select the monitor or monitor group for which you want to configure dependent device
Note:
1. Sub Group will override MG Group Dependent Device Configuration
2. Monitor level configuration will override all the Dependent Group(Monitor Group and Sub Group) level Dependency configuration
3. Configuring Dependent device at monitor group level is like configuring dependent device for each device under monitor group.
