Issue/Introduction

Our HUB queue alarms are being reported as a warning and this is supposed to be an Major Alarm. How do we change HUB alarm thresholds?

 

Environment

Release : 9.2.0

Component : UNIFIED INFRASTRUCTURE MGMT
HUB 9.x
PPM V 3.24

Resolution

You can set static alarm thresholds at the QoS metric level for some probes that publish alarms for a QoS metric. The following procedures explain how to configure some commonly used probes.
 To create dynamic alarm thresholds, first install and configure the baseline_engine probe version 2.0 or later on the hub robot.
For Hubs Running ppm v3.24 and Later
 
Follow these steps:
 
  • In the probe GUI, select a node in the tree to view any associated monitors and QoS metrics.
  • Select the monitor that you want to modify from the available list.
    Click 
    Publish Data
     and 
    Publish Alarms
    .
  • Click 
    Static Alarm
    . The Static Alarm options become available.
     If you cannot select the Static Alarm check box, click . If necessary, deploy or activate the baseline_engine probe.
  • Choose an operator for the threshold:
     
  •  
    An alarm occurs when the metric is greater than the set threshold.
  •  
    > = 
    An alarm occurs when the metric is greater than or equal to the set threshold.
  •  
     An alarm occurs when the metric is below the set threshold.
  •  
    <  =
     An alarm occurs when the metric is below or equal to the set threshold.
  •  
    =
     An alarm occurs when the metric is equal to the set threshold.
  •  
    !=
     An alarm occurs when the metric is not equal to the set threshold.
     If you used the threshold_migrator probe to add the static threshold fields for a probe, the operator and configured threshold carry over.
  • Set the threshold for each alarm state.
  • (Optional) Enter a different (overriding) Subsystem ID using the 
    Subsystem (override) field
    . The override is only required if the Subsystem ID shown in the
     Subsystem (default)
    field is not correct for your configuration.
    The override option is available with baseline_engine 2.1 or later.
  • (Optional) Create a custom alarm message for your environment:
     
  • In the Custom Alarm Message field, enter or select variables to include in a custom message.
    The available variables are:
    ${baseline} - The baseline that is calculated for a QoS metric when the 
    Compute Baseline
    option is selected for the metricBaselines are not calculated for static messages. The baseline value is always zero for static alarms.
    ${level} - The numerical severity level of the alarm
    Valid values are: 1 (critical), 2 (major), 3 (minor), 4 (warning), or 5 (information)
    ${operator} - The operator (>, >=, <, <=, ==, or !=) for the alarm severity level
    ${qos_name} - The name of the QoS metric${qos_source} or ${source} - The source of the QoS metric that generated an alarm${qos_target} or ${target} - The target of the QoS metric that generated an alarm${qosReference} - Adds the name of the QoS metric for which the time-to-threshold is configured${tttTime} - Adds sample time (in numerals only) for which the time-to-threshold is configured${tttTimeUnit} – Adds the time unit of ${tttTimes}${tttValue} – Adds the user input time-to-threshold Prediction Value${predictionValue} – Adds the predicted time at which the ${tttValue} is crossed. 
    ${threshold} - Specifies the threshold upon which an alarm is generated${threshold_sign} – Use this variable 
    before
     the ${threshold} variable to generate a + plus-sign when the threshold is a positive integer.
     
    ${threshold_symbol} – Use this variable 
    after
     the ${threshold} variable to generate a percent symbol for dynamic percentage thresholds or a sigma symbol for dynamic standard deviation thresholds.
    ${threshold_value} – If you want the evaluated threshold value, use this variable instead of the ${threshold} variable. For example, if the threshold is 5 percent of a baseline, which is 10, then the evaluated threshold value is 10.5.
    ${value} - Specifies the value that is contained in the generated QoS message
    For more information, see variable substitution
  • In the Custom Alarm Clear Message field, enter the message that is displayed when the alarm clears.
    The available variables include:
    ${qos_name} - The name of the QoS metric
    ${value} - Specifies the value that is contained in the generated QoS message
    ${source} - The source of the QoS metric that generated an alarm
