Fleet Manager best practices

Introduction

These Fleet Manager best practices have arisen directly from the experiences that our support team has had working with our customers.

Add Iguana servers at off-peak times [top]

  • Question: When is the best time to add Iguana servers to Fleet Manager?

    Adding new servers places a heavy load on Fleet Manager and can cause the interface to become slow or temporarily unresponsive. So we need to manage this process to minimize disruption to monitoring.

  • Answer: The best time to add Iguana servers is during off-peak times when the message load is lowest and monitoring requirements are minimal. In general this would probably be overnight in the early morning hours.

    Note: Iguana servers with smaller log history will load more quickly and cause less disruption. So you may be happy loading a new server with “only” 5-10GB of logs during normal hours, as it will catch up quite quickly — in around 10-20 minutes.

When you add an Iguana server all it’s historical logs are rapidly imported to Fleet Manager. This causes a heavy load which can cause the Fleet Manager interface to become temporarily unresponsive. Fleet Manager can handle about 50-100GB/hour of messages — so importing 100GB of logs can take several hours. Therefore it is a good idea to add servers during non-peak times when the least number off messages are being processed (by currently monitored channels). It is also a good idea to choose times when the Fleet Manager is least likely to be used (by people) for monitoring purposes.

  • Question: Should I add multiple Iguana servers to Fleet Manager at the same time?

    This depends on the total size of the historical logs to be imported — rather than the number of servers.

  • Answer: You can add one or more servers with a total of about 50-100GB of historical logs — if you are doing it at off-peak times.

    Note: If you are loading a server with smaller logs of “only” 5-10GB of logs you may be happy adding it during normal hours, as it will catch up quite quickly (in around 10-20 minutes).

When you add an Iguana server all it’s historical logs are rapidly imported to Fleet Manager. This causes a heavy load which can cause the Fleet Manager interface to become temporarily unresponsive. Fleet Manager can handle about 50-100GB/hour of messages — so importing 100GB of logs can take several hours. Servers with 50GB or more should probably be added separately — and also at off-peak times.

Managing peak message loads [top]

  • Question: What is the peak message load recommended for Fleet Manager?

    Fleet Manager can handle about 50-100GB/hour of messages,  depending on the hardware used and the network capacity.

  • Answers:
    • When Interface performance starts to become slow/unresponsive you may need to upgrade hardware or split monitoring over multiple Fleet Manager servers.
    • If Fleet Manager is not keeping up with importing all the records from attached Iguana servers — you may need to upgrade the network capacity.
