KEMP 360 Vision

 

Introduction

KEMP 360 Vision is a proactive application delivery monitoring and visibility service provided by KEMP to help customers optimize their application Infrastructure. The KEMP LoadMaster Application Delivery Controller (ADC) is in the ideal place in a network to provide an optimal view of application state. Metrics such as traffic load, server health, system throughput, concurrent connections, interface statistics, load distribution and system resource utilization provide the information needed to determine the health of application delivery.

Along with current application state, historical metrics provide valuable information in both evaluating the long-term health of application delivery, as well as optimization and capacity planning.

KEMP 360 Vision utilizes metrics collected to enable proactive health monitoring, customer alerts, data reporting, capacity planning and configuration optimization. KEMP 360 Vision takes customer support to a new level by proving 24x7x365 active monitoring of the customer’s ADC and proactively informing customers of potential application delivery issues. In the event of an application delivery issue, you will be notified by your chosen method, or methods, (by phone, email and/or SMS) and a KEMP support engineer will be engaged for assistance. This ensures minimum time to resolution and this proactive approach allows a large proportion of issues to be resolved before any potential service outages or user impacts occur.

Community String

Checks

Virtual Services

Maintenance Mode

In the Setup screen, you can enable Maintenance Mode. KEMP recommends enabling Maintenance Mode when performing any maintenance on your network or devices. When maintenance mode is on, no alerts are sent and you are not contacted about any issues. Ensure you disable maintenance mode when all maintenance is complete.

Maintenance Schedule

In the Maintenance Schedule section, specify a maintenance time period. Maintenance Mode will be enabled during the maintenance period specified.

Multiple maintenance periods can be specified. To delete an existing maintenance period, click the trashcan icon.

When maintenance mode is on, this screen displays Maintenance Mode On in red text.

LoadMaster IP/HA1IP/HA2IP

The IPaddress field name changes based on the type of LoadMaster added. When adding a LoadMaster, you choose either SINGLE, HA PAIR or CLOUDPAIR. For a single unit, the field name is LoadMaster IP. For a High Availability (HA) unit, the field label is either HA1IP or HA2IP.

If there are issues monitoring a LoadMaster, a red exclamation mark displays to the right of the IP address. If this is the case, try setting the Community String. Refer to the Community String section for instructions on how to do this. If KEMP 360 Vision can monitor the LoadMaster, a green tick will appear to the right of the IP address.

Community String

To enable monitoring of the LoadMaster, enable SNMP on the LoadMasters you want to monitor. Then, copy and paste the Community String from the LoadMaster into the KEMP 360 Vision Monitor.

To do this, follow the steps below in the LoadMaster Web User Interface (WUI):

Go to System Configuration > Logging Options > SNMP Options.

Select the Enable SNMP check box.

Copy the Community String value.

The default value of this field is public.

After copying the Community String from the LoadMaster, go to the Setup screen in the KEMP 360 Vision Monitor and paste the value into the Community String text box. Then, click SAVE SETTINGS at the bottom of the screen.

Checks

When expanded, the Checks section enables you to specify what checks to perform. A brief description of each check type is below:

System: Measures memory usage and CPU utilization of the HA1 LoadMaster (as defined when initially adding the cluster). If these are above recommended thresholds (configured by KEMP), it may indicate that the LoadMaster is operating close to its limits.

Interface Stats: Checks the statistics of the LoadMaster interfaces – particularly throughput levels (too high/too low) and high error/dropped packets. You can define throughput thresholds by contacting KEMP Customer Support.

Interfaces: Monitors the status of the LoadMaster interfaces configured for sending and receiving traffic. Possible statuses are up (OK) or down (critical).

Real Server Statistics: Measures Real Server connection statistics and determines if these are above defined thresholds. You can define the thresholds by contacting KEMP Customer Support.

Real Servers: Determines the status of Real Servers belonging to Virtual Services selected for monitoring. The Real Server health checks determine what the status is (Up or Down).

Reachability: Ensures the LoadMaster’s accessible interfaces are available. This includes HTTPS (WUI), SSH and PING. Failure would indicate loss of connectivity to one or more of the LoadMasters over these interfaces.

Virtual Service Statistics: Measures Virtual Service connection statistics and determines if these are above defined thresholds. You can define the thresholds by contacting KEMP Customer Support.

Virtual Services: Determines the Virtual Service status of those selected for monitoring. The Real Server health checks determine what the status is (Up or Down). The KEMP 360 Vision Monitor shows administratively disabled Virtual Services as up because this is an expected status.

Transactions: Measures Transactions per Second (TPS) and Secure Sockets Layer (SSL) TPS and compares to warning and critical values based on your LoadMaster model. If these are exceeded, it may indicate that the LoadMaster is operating close to transaction limits.

Virtual Services

The Virtual Services section enables you to specify which Virtual Services to monitor with KEMP 360 Vision. Select the Virtual Services and/or SubVSs to monitor.

Clicking the three dots to the left of a parent Virtual Service enables you to easily Select All SubVSs or Deselect All SubVSs for that Virtual Service.

Clicking the SAVE SETTINGS button at the bottom of the page applies and saves any configuration changes made in the Setup screen.

Syslog

In order to view the syslog messages in the KEMP 360 Vision Monitor, you must first configure the syslog settings in the LoadMaster.

Configure the Syslog Settings in the LoadMaster

To configure the syslog settings on the LoadMaster, follow the steps below in the LoadMaster WUI:

Go to System Configuration > Logging Options > Syslog Options.

Enter the IP address of the KEMP 360 Vision instance into each of the Host text boxes.

If you already have a syslog server in use, the KEMP 360 Vision Monitor IP address can be appended to the existing addresses. Do this by adding the IPaddress after the existing addresses using a space-separated list.

Click Change Syslog Parameters.

View the Syslog Messages in the KEMP 360 Vision Monitor

When the LoadMaster is configured to send syslog messages to KEMP 360 Vision, the Syslog screen in KEMP 360 Vision shows syslog messages from the LoadMaster. You can search for a particular term in the search box to narrow down the logs. Clicking the DOWNLOAD LOG button downloads a copy of all log files (regardless of what is filtered in the UI) to your local machine.

Status

The Status screen displays messages about the Real Server, Virtual Service, interface and system statuses, depending on what checks you enabled.

Enabling the Auto refresh toggle ensures that the Status screen is updated with any new messages every 10 seconds.

Reporting

The Reporting section provides different reports for VIRTUAL SERVICES, SYSTEM, TRANSACTIONS and HIGH AVAILABILITY.

Virtual Services

The Virtual Services report displays the status for each monitored Virtual Service on each day in a calendar month:

Red: The Virtual Service was down on that day

Green: The Virtual Service was up on that day

Combination of red and green: The Virtual Service was both in an up and down status throughout the day.

White: The Virtual Service was not being monitored on that day

Grey: Future date

System

The SYSTEM screen has two charts to show CPU load and memory used over a period of time. Examples of each are provided below.
