HP-UX Cluster

Introduction

HP-UX, provided by Hewlett Packard Enterprise, is a robust and secure Unix-based operating system designed specifically for HP’s servers. Based on the Unix System V architecture, HP-UX offers a stable and highly scalable environment for enterprise workloads. It is one of the few commercial operating systems certified under UNIX 03 standards, adhering to the strict compliance and reliability requirements of high-end enterprise environments.

Features of HP UX integration

• HP-UX systems can be automatically discovered and onboarded into the OpsRamp platform, ensuring seamless integration and minimal manual intervention.
• Configurable alert policies help IT teams stay ahead of issues with instant notifications and detailed reporting, allowing for proactive management.
• Through resource monitoring and utilization insights, OpsRamp helps optimize the performance of HP-UX systems by identifying bottlenecks or resource constraints.
• Access to intuitive dashboards that provide key metrics, enabling system administrators to monitor CPU usage, memory utilization, disk activity, and network performance in real-time.

Hierarchy of HP UX Integration

For HP-UX Cluster, the hierarchy is as follows:

• HP UX Cluster
• HP UX Server
• HP UX Resource Group

• HP UX Server

Prerequisites

• OpsRamp Classic (Linux) Gateway 15.0.0 and above.
• OpsRamp Nextgen Gateway 15.0.0 and above.
• Better to go to latest Gateway version to full coverage of (Recent bug fixes, enhancements.. etc).
• Customer need to provide HP-UX Cluster IpAddress and SSH login credentials (This credentials should be same for all nodes).
• HP-UX Cluster nodes should be reachable from the gateway and SSH access must be opened.
• The assigned SSH credentials should have privileges to execute CLI commands. Note: /usr/sbin path must be configured on the target cluster nodes to execute CLI commands. (Execute this command to set path: export PATH=$PATH:/usr/sbin).
• This SDK app applicable to HP-UX Cluster environment (which is running on Serviceguard Cluster Software).

Supported versions

• HP-UX Cluster : Installed Cluster Software - Serviceguard Manager version : B.03.00 & Serviceguard version : A.11.20.00

Migration details

1. Check for the gateway version as a prerequisite step - classic gateway-12.0.1 and above.
   Notes:

   • You only have to follow these steps when you want to migrate from sdk 1.0 to sdk 2.0.
   • For first time installation below steps are not required.
     • Application name should be the same.
     • Disable all installed integrations configurations for that application. This is to make sure no discovery and monitoring requests are processed.
     • Install and Add the configuration to that sdk 2.0 application.
     • During the migration from SDK 1.0 to SDK 2.0, ensure that you uncheck the Bypass Resource Reconciliation checkbox.
       Note: Refer to Configure and Install the HP UX Server Integration & View the HP UX Server Details sections of this document.

2. Once all discoveries are completed with the sdk 2.0 applicaion, follow any one of the approaches.

   • Direct uninstallation of the sdk1.0 adaptor application through the uninstall API with skipDeleteResources=true in the post request

Supported Metrics

Default Monitoring Configurations

HP UX Cluster have default Global Device Management Policies, Global Templates, Global Monitors and Global metrics in OpsRamp. User can customize these default monitoring configurations as per their business usecases by cloning respective global templates and global Device Management Policies. OpsRamp recommend to do this activity before installing the app to avoid noise alerts and data.

1. Default Global Device Management Policies available OpsRamp will have a Global Device Management Policy for each Native Type of IBM AIX Cluster. We can find those Device Management Policies at Setup -> Resources -> Device Management Policies -> Search with suggested names in global scope. Each Device Management Policy follows below naming convention: {appName nativeType - version - Type} Ex : hp-ux-server HP UX Cluster - 4 - HP-UX Cluster (i.e, appName = hp-ux-server, nativeType = HP UX Cluster, version = 4, Type = HP UX Cluster)

2. Default Global Templates available OpsRamp will have a Global template for each Native Type of IBM AIX Server. We can find those templates at Setup -> Monitoring -> Templates -> Search with suggested names in global scope. Each template follows below naming convention : {appName Type nativeType ‘Template’ - version} Ex : hp-ux-server HP UX Cluster Template - 4 g(i.e, appName = hp-ux-server, Type = HP UX Cluster, nativeType = HP UX Cluster, version = 4)

3. Default Global Monitors available OpsRamp will have a Global Monitors for each Native Type which has monitoring support. We can find those monitors at Setup -> Monitoring -> Monitors -> Search with suggested names in global scope. Each Monitors follows below naming convention : {monitorKey appName nativeType - version} Ex : HP UX Cluster Monitor hp-ux-server HP UX Cluster 4(i.e, monitorKey = HP UX Cluster Monitor, appName = hp-ux-server, nativeType = HP UX Cluster, version = 4)

Risks, Limitations & Assumptions

• Application can handle Critical/Recovery failure notifications for below two cases when user enables App Failure Notifications in configuration:
  • Connectivity Exception
  • Authentication Exception
• Application uses the provided IpAddress/hostname, Credentials for SSH communications.
• Application will send duplicate/repeat failure alert notification for every 6 hours.
• Application cannot control monitoring pause/resume actions based on above alerts
• Metrics can be used to monitor HP UX Server resources and can generate alerts based on the threshold values.
• OpsRamp has provided 22 as default SSH Port value for connecting to HP UX end devices via SSH. Users can modify this value from the application configuration page at any point of time if required.
• No support of showing activity logs.
• The Template Applied Time will only be displayed if the collector profile (Classic and NextGen Gateway) is version 18.1.0 or higher.
• Full discovery support requires gateway version 15.0.0 or above.
• This application supports both Classic Gateway and NextGen Gateway.
• Currently we do not have monitoring support for below things
  • Hardware metrics
  • Programmable Resource Monitoring
  • Processes (We provided one metric for each process RunningStatus. i.e, hpux_server_process_RunningStatus)
• For log monitoring, we expect the below json payload as input.
  • “Name” can be any string used to identify individual log configuration.
  • “File Name” is a combination of folder path and file name. Folder path should contain the exact path for the file as prefix. File name can be any valid string or regular expression.. In case of file not found with specified file name, alert will be generated with the severity specified by the user.
    Example 1: C:\Program Files (x86)\Vistara\Agent\log\Age.?t.log
    Matches: Agent.log, Ageat.log ,..
  • “Rotated File Name” is similar to filename field but specifying the rotated file. This field is optional.
  • “Expression” can be any valid string or regular expression used to specify the search string. It’s a mandatory field.
  • “Check Type” can be either “exists” or “not exists”(case insensitive).
  • “Threshold” can be any valid integer. Alert will be generated in case a specified threshold breach happens.
  • “Severity” used to specify the alert type to be created in case of expression found. Possible values are CRITICAL,WARNING,INFO and OK (case insensitive).
  • Log file monitoring is supported only for HP UX Server Type which must be selected in the configuration

Log File configuration
[
  {
  "Name":"",
  "File Name":"",
  "Rotated File Name":"",
  "Expression":"",
  "Check Type":"",
  "Threshold":"",
  "Severity":""
  }
]

• We do not process logs of size greater than 1GB.
• We do not process logs for the first request, since it leads to performance issues due to huge data. We will consider the latest logs ( logs generated between first and second polls) from the second request and process accordingly.
• No recovery alerts are generated for expression related alerts. We will get recovery only for file not found alerts.

Troubleshooting

Before troubleshooting, ensure all prerequisites prerequisites are met.

If HP-UX integrations fail to discover or monitor, troubleshoot using the following steps:

• Check if any alerts have been generation on HP-UX Server Resource, the gateway, or in vprobe.
• If there is an error or alert related to the end device connectivity or authentication, try checking the reachability of the end device from the gateway with the following commands:
  • to ping the IP address provided in the configuration: {ping <IP Address>}
  • to try telnet: {telnet <IP Adress> <Port>}
  • To run a SSH command:

    • Prepare the request payload by using below sample request:

      { “apiVersion”: “debug/v1”, “module”: “Debug”, “app”: “hp-ux-server”, “action”: “Reachability”, “payload”: { “ipAddressOrHostName”: “”, “protocol”: “https”, “port”: 443, “requestPath”: “”,

      “version”:“v1”,

      “requestMethod”:"<get/post>", “userName”: “”, “password”: “” } }

    • Encode the request payload to base64

    • Log in to the gateway concole and connect to the GCLI terminal using the below command: {## gcli}

    • Run the command using the previously generated base64 encoded string {## sdkappdebug <base64 encoded string>}
