ibm_svc_AC
This article describes the configuration concepts and procedures to set up the IBM SVC Monitoring (ibm_svc) probe. You can configure monitors to generate QoS and alarms once the probe establishes a connection with the IBM SVC or V7000 storage system.
The following diagram outlines the process to configure the probe.

Verify Prerequisites
The preconfiguration requirements of the probe are as follows:
  • A user account to access the web interface and command interpreter of the IBM System Storage SAN Volume Controller (SVC). You must have the privileges to retrieve the data from the storage server using SMI-S and CLI.
  • Verify that required hardware and software is available before you configure the probe. For more information, see ibm_svc (IBM SVC Monitoring) Release Notes.
Configure Log Properties
You can configure the log properties of the probe to define the amount of log information to maintain.
 
Follow these steps:
 
  1. Click the
     ibm_svc
     node.
  2. Set or modify the following information, as required.
    •  
      Log level:
       specifies the level of information that is written in the log file.
      Default: 5 - Trace
       Log as little as possible during normal operation to minimize disk consumption, and increase the amount of detail when debugging.
  3. Click 
    Save
     to save the probe configuration.
Create a Profile
You can create profiles to monitor the storage systems. Each profile uses a connection to an IBM SVC or V7000 storage system to collect and store monitoring data. 
 
Follow these steps:
 
  1. Click the 
    Options (icon)
     next to the 
    ibm_svc
     node.
  2. Select 
    Add New Profile
    .
    The 
    Add New Profile
     dialog appears.
  3. Specify the following information:
    •  
      Hostname
      : specifies the hostname or the IP address of the storage system.
    •  
      Port
      : specifies the port number that the probe uses to connect to the storage system.
      Default: 443
      Specify 5988 as the port number to connect to the storage system. Use 5989 as the port number for a secure connection to the storage system.
    •  
      Username
      : specifies the username to access the storage system.
    •  
      Password
      : specifies the password of the defined 
      Username
      .
    •  
      Active
      : activates the profile to start monitoring the storage system, on creation.
      Default: Selected 
    •  
      Interval (secs):
       specifies the interval after which the probe again retrieves data from the storage system.
      Default: 600
      Reduce this interval to generate alarms and QoS frequently. A shorter interval can also increase the system load.
    •  
      Alarm Message
      : specifies the alarm message to be generated when the probe is unable to connect to the storage system.
      Default: ResourceCritical 
    •  
      Use SSL
      : allows the probe to use HTTPS to connect to the storage system.
      Default: Not selected 
    •  
      namespace
      : displays 
      root/ibm
       as the namespace of the storage system. This field is read-only. 
    •  
      Storage Type
      : specifies the storage type to monitor.
      Default: SVC 
  4. Click 
    Submit
     to create the profile.
    The profile is created as a 
     
    Profile Name
     
     node under the 
    ibm_svc 
    node.
  5. Navigate to the 
    P
     
     
    rofile Name
     
    node.
  6. Click 
    Test Connection
     from the 
    Actions
     drop-down to test the connection with the storage system.
    A dialog appears displaying a successful connection.
  7. Click 
    Save
    .
    The profile is saved and the IP address of the resource is displayed under the 
    ibm_svc
     node. You can select the 
    IP Address
     node to configure the monitors.
 
  • To delete a profile, click the 
    Options (icon)
     on the 
     
    IP Address
     
     node and select 
    Delete Profile
    , and 
    Save
     the configuration.
  • To view the cluster hierarchy of the storage system, expand the 
    Clusters
     node and view various elements such as Disk Controllers, Hosts, IO Groups, MDisk, MDisk Groups, Nodes, Ports, and VDisk and devices with other physical elements of the IBM SVC or V7000 storage systems.
Configure Monitor Properties
You can configure the probe monitors to set up alarms and QoS. The nodes in the profile tree under 
Clusters
 node have numeric and string monitors.
  •  
    Numeric monitors
    : You can set up alarms conditions and QoS messages for monitors that generate numeric metric data.
  •  
    String monitors
    : You can set up alarm conditions for monitors that generate string metric data. String type monitors do not generate QoS messages.
 
Follow these steps:
 
  1. Navigate to the required node.
  2. Select the required monitor to configure its properties. For example, to configure the 
    Available Capacity
     monitor for a cluster, navigate to the 
    cluster name
     node under the 
    Clusters
     node. You can define the alarm conditions and QoS messages for this monitor.
  3. Select the
     Publish Data
     and 
    Publish Alarms
     to retrieve QoS data and generate alarm messages, respectively.
  4. Specify the following values for numeric and string monitors, as required:
    •  
      Monitor (Numeric)
      •  
        Value Definition: 
        specifies the type of value for comparison with the threshold value and generate alarms. This value type is also used in the QoS messages.
        •  
          Current Value:
           uses the current (last measured) value to compare it with the threshold value.
        •  
          Average Value Last n Samples: 
          uses the average of the measured values of the defined 
          Number of Samples
        •  
          Delta Value (Current - Previous):
           uses the delta value for comparison with the threshold value. The delta value is the difference between the current and the previous measured value.
        •  
          Delta Per Second:
           uses the delta value per second for comparison with the threshold value. 
        For the
         Average Value Last n Samples, Delta Value
        , and 
        Delta Per Second 
        fields, the probe generates QoS and alarms after the defined 
        Number of 
         
        Samples
         are complete. For example, if 
        Average Value Last n Samples
         is selected and the samples are defined as four, the probe collects data for the four samples before generating any QoS or alarm.
      •  
        Number of Samples: 
        specifies the number of values for the probe metric calculations to generate QoS and alarms.
    •  
      Monitor (String)
      • High Operator: 
        select an operator to match the retrieved value with the threshold for the maximum limit. The operator can be either 
        (equal to) or 
        !=
         (not equal to).
        Default: !=
      • High Threshold: 
        specifies the maximum threshold for the monitor.
      • High Message Name: 
        specifies the alarm message to display when the threshold breaches the maximum limit.
        Default: MonitorError
      • Low Operator: 
        select an operator to match the retrieved value with the threshold for the minimum limit. The operator can be 
        disabled
        (equal to), and 
        !=
         (not equal to).
        Default: disabled
      • Low Threshold: 
        specifies the minimum threshold for the monitor.
      • Low Message Name: 
        specifies the alarm message to display when the threshold breaches the minimum limit.
  5. Click 
    Save
     to save the configuration.

Alarm Thresholds
The alarm threshold options that are available can vary depending on the probe versions installed at the hub level. The alarm threshold settings to allow the probe to:
  • Send alarms when threshold criteria is met
  • Indicate to baseline_engine to compute baselines
See Configuring Alarm Thresholds for details.
Stop Receiving Alarms for Deleted Components
Use this procedure to stop receiving alerts for any monitored component that you delete from your storage system.
For example, a monitored port is deleted from the storage system, before its monitoring is deactivated. The probe keeps sending false alarms for the port because the probe is not able to retrieve the port details. The port is also not visible on the probe GUI navigation pane.
 
Follow these steps:
 
  1. Navigate to the 
    Detached Configuration
     node. This node contains the components that are deleted from the storage system but are still monitored from the probe.
  2. Click the 
    Options
     
    (icon)
     next to the component name you want to stop receiving alerts and select 
    Delete
    .
  3. Click 
    Save
    .
The probe stops sending false alerts for the deleted components.
