Monitoring Windows Server Storage Utilization with Nectus

In this chapter, you’ll learn how to use WMI to monitor Windows Server Storage Utilization. Nectus lets you create Profiles that specify which Servers to monitor with WMI and to send Alerts related to them. It also provides graphs of Server Utilization over time.

The specific topics we will cover in this chapter are:

  1. What is WMI?
  2. Why Monitor Windows Server Storage Utilization?
  3. Creating a WMI Server Group
  4. Adding a Server to the WMI Server Group
  5. Creating and Configuring a WMI Monitoring Profile
  6. Assigning a Profile to the WMI Server Group
  7. Viewing a Storage Utilization Graph

1. What is WMI?

WMI (Windows Management Instrumentation) is a set of specifications and interfaces that provides information about the status of local and remote computers running Microsoft Windows. In this chapter we look at how Nectus uses WMI to monitor the Storage Utilization on Windows Servers and send Alerts based on that information.

Note: WMI is the Microsoft implementation of the Web-Based Enterprise Management (WBEM) standard and the Common Information Model (CIM) standard from the Distributed Management Task Force (DMTF).

2. Why Monitor Windows Server Storage Utilization?

Monitoring when Storage Utilization goes outside of the expected Thresholds alerts you to various problems. For example, exceeding the Maximum Threshold could indicate that a Server needs a larger disk, or that some other application is using space on the disk. Utilization below the Minimum Threshold could indicate that data is not being received by the Server, or a problem is keeping the data from being written to the disk.

3. Creating a WMI Server Group

To create a WMI Server Group open the WMI Servers Panel on the Nectus Home Screen. Right-click the WMI Servers list. In the menu that appears, click Add New Group.

This opens the “Add New WMI Server Group” dialog box.

Enter a Group Name, then select the Email Groups and SMS Groups that will receive Alerts.

4. Adding a Server to the WMI Server Group

To add a Windows Server to the WMI Server Group right-click the Group and select Add New WMI Server.

This opens the “Add WMI Server” dialog box.

Enter the IP address of the Server you want to add to the Group. Alternately, you can move a Server from its current Group to this Group by right-clicking the Server and using the Move WMI Server to option.

5. Creating and Configuring a WMI Monitoring Profile

To create a WMI Monitoring Profile go to the Nectus Home Screen and select Monitoring -> WMI Monitoring Settings.

This opens the “WMI Monitoring Settings” dialog box.

Click Add Profile -> Disk.

Enter the Monitoring Profile Name and check the Enabled box next to the Disk Used Space metric. Check the types of Alerts you want the Profile to send.

Check the Default Profile box if you want to make this the new default WMI Monitoring Profile.

5.1 Editing Disk Used Space Options

Select the Disk Used Space Options icon to open the “WMI Options – Disk Used Space, %” dialog box.

Set the Alert Thresholds you want to monitor, as well as the number of Consecutive Readings that a Threshold must be exceeded before triggering an alert. Nectus checks the thresholds every 5 minutes, so setting Consecutive Readings to 3 means a value would need to exceed the assigned Threshold for 15 minutes before triggering an alert.

5.2 Editing Disk Used Space Alert Templates

To edit the format of Alerts return to the Disk tab of the “Add WMI Monitoring Profile” dialog box. Click the Disk Used Space Alert Templates icon to open the “Edit Alert Handler” dialog box.

6. Assigning a Profile to the WMI Server Group

In the WMI Servers Panel on the Nectus Home screen, open the WMI Servers list. Right-click the WMI Server Group and select Properties.

This opens the “Edit WMI Server Group” dialog box.

Select the WMI Monitoring Profile to use from the Monitoring Profile drop-down list.

7. Viewing a Storage Utilization Graph

To view a graph of Storage Utilization over time, right-click the Server you want information on and select Disk Used Space Graph.

This opens a “Disk Used Space Graph” which displays the changes in Storage Utilization over time.

 

Monitoring DHCP Scope Utilization on Windows DHCP Servers with Nectus

, ,

Monitoring Scope Utilization on Windows DHCP Servers with Nectus

In this chapter, you’ll learn how to use Nectus to enable and configure DHCP Scopes utilization monitoring on Windows DHCP Servers.

Nectus allows network engineers proactively monitor amount of free IP addresses in DHCP scopes and generate E-mail or Text alerts when number of free IP address falls below preset thresholds.

Nectus can also generate alert when number of free IP address exceeds predefined threshold as it may indicate underlying network operation problems when network devices not able reach DHCP server for leases.

Nectus uses basic WMI interface to collect scope and lease statistics from DHCP servers.

The specific topics we will cover in this chapter are:

  1. What is WMI?
  2. Why Monitor DHCP Scopes?
  3. Creating a DHCP Server Group
  4. Adding DHCP Server to Server Group
  5. Creating and Configuring Monitoring Profile
  6. Assigning Monitoring Profile to Server Group

1. What is WMI?

Nectus uses Windows Server WMI interface to collect basic information about DHCP scopes such as total number of IP addresses and current number of active leases.

WMI (Windows Management Instrumentation) is a set of specifications and interfaces that provides information about the status of local and remote computers running Microsoft Windows. In this chapter we look at how Nectus uses WMI to monitor DHCP Scope Utilization  and send alerts based on that information.

Note: WMI is the Microsoft implementation of the Web-Based Enterprise Management (WBEM) standard and the Common Information Model (CIM) standard from the Distributed Management Task Force (DMTF).

2. Why Monitor DHCP Scopes?

Availability of free IP addresses is a critical requirement for modern network. When DHCP scope runs out of addresses users are not able to join your network.

Typical network segments that heavily dependent on DHCP are LAN and Wi-Fi Users.

Several DDOS attack types are specifically targeting DHCP infrastructure and by exhausting DHCP pools with fake lease requests can bring down any network to its knees.

Sometimes regular business growth can cause corresponding grows in IP address utilization and if left undetected can eventual cause an outage and service degradation for DHCP dependent applications.

3. Creating a DHCP Server Group

First step is to create a new Server Group for our DHCP Servers.

Go to the Nectus Home Screen and select WMI Servers -> WMI Servers. In the menu that appears, click Add New Group.

This opens the “Add New WMI Server Group” dialog box.

Complete the fields that define the new Group and set Enable Monitoring.

4. Add a DHCP Server to Server Group

Now we need to define our DHCP Server and add those to Server Group.

To add a Windows DHCP Server to the Server Group right-click the Group and select Add New WMI Server.

This opens the “Add WMI Server” dialog box.

Enter the IP address of the Server you want to add to the Group.

Note: You can move a Server between different Groups by right-clicking the Server and using the Move WMI Server to option.

5. Creating and Configuring Monitoring Profile

Monitoring Profile is a list of Metrics that can be applied to Server Group to tell Nectus which specific metrics must be monitored for given Server Group.

To create new Monitoring Profile to go Monitoring -> WMI Monitoring Settings and press

“Add Profile” button

Monitoring Profile Configuration Interface will appear.

Assign Profile Name and enable “DHCP Scope Usage” check-button on “DHCP” Tab

Configure Max/Max Threshold Values for Alerts by pressing on “Options” button

Note: Monitoring Interval is 5 min therefore 3 for “Consecutive Readings” value will trigger Alert

only if Threshold condition are True for 15 minutes.

6. Assigning Monitoring Profile to Server Group

Next and the final step is to assign Monitoring Profile to the DHCP Server Group that we created.

Right Click on DHCP Server Group in left side panel and Select “Properties”

Select Monitoring Profile from the list of available Profiles and Click on “Enable Monitoring” check-button.

We are all set and ready to start proactive monitoring of your DHCP Infrastructure.
