NMIS

NMIS (Network Management Information System) is a complete network management system which assists with fault, performance and configuration management, providing performance graphs and threshold alerting as well as highly granular notification policies with many types of notification methods. NMIS monitors the status and performance of an organization’s IT environment, assists in rectification and identification of faults and provides valuable information for IT departments to plan expenditure and IT changes.

opLicense

The opLicense module on your NMIS server is used to provide you with an overview of your current product installation and license states. The standard URL is http://<your_system_name_or_ip>/omk/opLicense/, and the view will include all installed and activated products and their license status similar to the following:


All products on the appliance (except opFlow) support free licenses (which are not time-limited but limited to 20 nodes). For these applications the initial dialog offers the generation of such a free license; for opFlow the licensing dialog offers guidance for obtaining a trial or a full license. Example screen shot of activating free Open-AudIT trial below:


Single module vs bundle licensing

Typically licenses are provided in bundles which can be applied via the opLicense module on your server. Applying a bundle license requires internet access as you will be prompted to enter your opmantek username and password.

There may be occasions where you want to only update a single module or you don’t have internet access. To upgrade your licenses in this case, you need to install each module's license key separately. The license key for each module can be found by logging into your account at opmantek.com. To apply a single license key, simply copy the license key, select the “Enter a License Key” option in opLicense and paste the key into the panel provided.




opCharts

Interactive Dashboards and Charts - through the use of user-defined metadata, opCharts combines and sorts devices into dynamic groups providing key performance metrics at every level. opCharts’ built-in ability to roll-up and provide high- level abstracted user views, while still allowing quick drill-down into detailed performance metrics, provides fast access to information to those who need it most. Developed to display large amounts of data through a dynamically responsive interface, opCharts allows users to see the live state and history of all systems all on the same page. Dashboard creation is simple, offering the ability to create custom displays quickly, with any level of detail, map every server across the world to a building, floor, server room or rack. Using the schema-driven design, you can group your nodes by role, type, status, location, characteristic or customer and limit their access based on your defined user privileges.

Installation

opCharts is distributed in a self-extracting download format that simplifies the installation process. 

Transfer the opCharts installer file onto the server in question, either by direct download from the Opmantek website, or from your desktop with scp or sftp or a similar file transfer tool.

  • Start the interactive installer and follow its instructions:

    sudo sh ./opCharts-Linux-x86_64-4.0.0.run
    ...
    ++++++++++++++++++++++++++++++++++++++++++++++++++++++
    opCharts (4.0.0) Installation script
    ++++++++++++++++++++++++++++++++++++++++++++++++++++++
    ...
    This installer will install opCharts into /usr/local/omk.
    To select a different installation location please rerun the
    installer with the -t option.
    ...

  • The installer will interactively guide you through the steps of installing opCharts. Please make sure to read the on-screen prompts carefully.
  • When the installer finishes, opCharts is installed into /usr/local/omk, and the default configuration files are in /usr/local/omk/conf, ready for your initial adjustments.
  • A detailed log of the installation process is saved as /usr/local/omk/install.log, and subsequent upgrades or installations of other Opmantek products will add to that log file.

Traffic light system

When you view the status of a node, you will see it’s displayed as either Green (Reachable), Yellow (Degraded) or Red (unreachable). This is commonly referred to as the Opmantek traffic light system. 

  • Green = Good/healthy. No issues detected with this device.
  • Yellow = Potentially unhealthy. Device is still reachable and working but has detected issues that should be investigated.
  • Red = Device cannot be reached and monitored by NMIS. This device should be investigated as it’s likely to have a major issue.
  • No labels
