Dynatrace Managed hardware and system requirements

This topic explains the hardware and operating system requirements for installing Dynatrace Managed.

Hardware requirements

It's not always possible to provision nodes that are sized exactly right, particularly if your environment is subject to ever-increasing traffic levels. While it's useful to do upfront analysis of required size, it's more important to have the ability to add more capacity to your Dynatrace Managed cluster should your monitoring needs increase in the future. To leverage the full benefits of the Dynatrace Managed architecture, be prepared to scale along the following dimensions:

  • Horizontally by adding more nodes
    • For Managed versions 1.168 and higher, we support installations of up to 12 cluster nodes.
    • Earlier Managed versions only support up to 6 cluster nodes.
  • Vertically by provisioning more RAM/CPU per node
  • In terms of data storage, by being able to resize the disk volumes as required (for guidelines regarding recommended disk setup see below).

Storage recommendations

Dynatrace Managed stores multiple types of monitoring data, depending on the use case. We recommend:

  • Storing Dynatrace binaries and the data store on separate mount points to allow the data store to be resized independently.
  • Not keeping Dynatrace data storage on the root volume to avoid additional complexity when resizing the disk later, if required.
  • Mounting different types of data storage on separate disk volumes for maximum flexibility and performance.
  • Creating resizable disk partitions (for example, by leveraging Logical Volume Manager [LVM]).

The hardware requirements included in the following table are estimates based on typical environments and load patterns. Requirements for individual environments may vary.

Node type Max hosts monitored (per node) Peak user actions/min (per node) Minimum node spec1 Disk IOPS (per node) Transaction Storage2 (for 10 days code visibility) Long-term Metrics Store3 (per node) Elasticsearch (per node and for 35 days retention)
Trial 50 1000 4 vCPUs, 32GB RAM 30 50GB 100GB 50GB
Small 300 10000 8 vCPUs, 64GB RAM 100 300GB 500GB 500GB
Medium 600 25000 16 vCPUs, 128GB RAM 300 600GB 1TB 1.5TB
Large 1250 50000 32 vCPUs, 256GB RAM 750 1TB 2TB 1.5TB
XLarge 2500 100000 64 vCPUs, 512GB RAM 1500 2TB 4TB 3TB

1 CPU and RAM must be exclusively available for Dynatrace. Power saving mode for CPUs must be disabled. CPUs must run with a clock speed of at least 2GHz.
2 Transaction data is distributed across all nodes and is not stored redundantly. So for multi-node clusters, the storage per node is divided by the number of nodes.
3 For multi-node installations we keep three copies of the metrics store. For 4 or more nodes the storage requirement per node is reduced.

Also see the directory structure of Dynatrace Managed.


  • To monitor 8k hosts with a peak load of 3k user actions per second, you need 3 extra large nodes with a combined storage of 4TB for direct storage and 30TB for long-term metrics.

  • To monitor 200 hosts with a peak load of 500 user actions per second, you need 1 medium node with storage of 1TB for transactions and 2.5TB for long-term metrics,or to have failover you can also use 3 small nodes.

Multi-node installations

We recommend multi-node setups for failover and data redundancy. A sufficiently sized 3-node cluster is the recommended setup. For Dynatrace Managed installations with more than one node, all nodes must:

  • Use the same Linux distribution
  • Have the same hardware configuration
  • Be synchronized with NTP
  • Be in the same time zone
  • Be able to communicate over a private network on multiple ports

System requirements

  • You'll need a dedicated host for Dynatrace Managed installation. This host must not run other services that are CPU or memory intensive, or that open ports used by Dynatrace Managed.

  • You need a 64-bit Linux distribution (see supported Linux distributions below). Note that installation on both physical and virtualized hosts is supported, but installation in containers isn't supported.

  • Dynatrace Server requires a fixed IP assignment.

  • Ensure that you've appropriately configured your firewall settings

  • The libraries that are installed with Dynatrace Managed are locale-aware. For correct display of text and symbols, be sure to set your environment's system locale to an English language option (for example, LANG=en_US.UTF-8).

Supported operating systems

Operating system Versions
Red Hat Enterprise Linux1 6.x - 7.x
CentOS 6.x - 7.x
Ubuntu 12.04 - 16.x, 18
openSUSE 12.x - 13.x
SUSE Enterprise Linux 11.3 - 12.x
Oracle Linux Server 6.x - 7.x
Amazon Linux AMI 2017.x - 2018.x, 2.x

1Redhat Enterprise Linux 7.4 & 7.5 must be amended.

Supported file systems

Dynatrace Managed operates on all common file systems. We recommend that you select fast local storage appropriate for database workloads. High latency remote volumes like NFS or CIFS aren't recommended. While NFS file systems are sufficient for backup purposes, we don't recommend them for primary storage.

Amazon Elastic File System

We don't support or recommend Amazon Elastic File System (EFS) as a main storage for Elasticsearch. Such file systems don't offer the behavior that Elasticsearch requires, and this may lead to index corruption.
