System status

The status of various components of the FusionReactor Cloud system can be seen here.

Missing, incomplete or malformed data

Network issues

FusionReactor is designed to be resilient to connectivity issues when shipping data to FusionReactor Cloud.

If your instance of FusionReactor has connectivity issues up to 60 mins of data is kept locally, once connectivity has been restored this data will be shipped intelligently in order to refrain from 'overloading' the transport system.

Data will then appear to 'back fill' and gaps in the data will be removed.

Agent configuration

For the most part FusionReactor is designed to be self-configuring. However in some cases specific configuration maybe required to tune certain collected information such as application or transaction names.

The FusionReactor Documentation contains useful information regarding this type of configuration.

FusionReactor settings

Live functionality not working correctly

Some functionality of FusionReactor Cloud requires a web socket connection to communicate directly with the FusionReactor instance. Examples of this functionality are recent or running transactions and the live graphing modes.

If you are experiencing issues with these areas of the software then you should refer to the following sections of this guide.

Connection issues

The Cloud status icon in the top right corner of FusionReactor shows the current connection status of the FusionReactor instance to the cloud.


Description State Icon
Agent connected and last transmission was successful Connected
Agent connected and last transmission was not successful Degraded
Agent disconnected and last transmission was successful Degraded
Agent disconnected and last transmission was unsuccessful Disconnected

Reasons for connection troubles included; network or internet connection issues, incorrect firewall or detailed view settings or system failure.

Proxy configuration

If you have a proxy server in place to access the internet, then you can configure it inside FusionReactor.


See this section of the FusionReactor documentation for more information on how to configure your proxy settings.


Some users run FusionReactor behind restricted firewalls which do not allow all outbound connections. In this case, these users may need to add specific firewall rules to allow FusionReactor to communicate with FusionReactor Cloud.

Using DNS Firewall Rules

In order to communicate with FusionReactor Cloud, each FusionReactor instance attempts to connect to the following services, which are identified by their DNS names:

These services require outgoing firewall rules for FusionReactor to communicate with FusionReactor Cloud. All communications are protected by SSL cyphers.

If possible, the firewall should be configured with the DNS names of these services, since they can change in response to scaling events.

If the IP addresses are required, nslookup can be used to find their current values. Most services will yield two addresses: both must be added.

Using Static IP Addresses

If you are unable or unwilling to use the dynamic DNS rules above, we have provided a static IP addresses which can be used for all services. - port tcp/443.

After enabling this firewall rule, the following -D options need to be applied to your JVM environment, to instruct FusionReactor to use the single address:




Locked-Down Environments

If you are using a non-standard Java security policy, you may have to add rules to it to allow FusionReactor to connect to these services. The form of these rules is:

permission "", "connect, accept, resolve";

permission "", "connect, accept, resolve";

permission "", "connect, accept, resolve";

permission "", "connect, accept, resolve";

Please see this FusionReactor technote for more information on configuring your firewall settings inside FusionReactor.
