Hostname

Metric value

Custom pattern

Data source

The threshold values came from the data source, AppInternals Xpert.

The absolute worst response time in the dashboard's time range was 1.5 minutes.

The gauge is actually showing the minimum maximum value.

The gauge's value is the average of the maximum servlet response times for the dashboard's time interval.

Select all of the desired metrics at panel creation time.

Click on the "+" icon on the panel after you have chosen an initial set of metrics.

Drag one panel on top of another to merge them.

After you select a host in the search field

From the sidebar only

By right-clicking on the main page

By right-clicking a tab

You get of list of next-hop IP addresses or host names to use to create dashboards.

The field automatically populates with the data sources for the IP address or host names from which you can open pre-configured dashboards.

The "Create New Dashboard" panel opens with templates you can use to create a dashboard with the given IP address or host name.

The dashboards already created with the given IP address or host name automatically open in a new tab.

Enable the X-Forwarded-for field.

Route clients around the load balancer.

Create a firewall rule to ensure the client IP addresses are seen.

Specify a route in the router for the client IP addresses.

Use the built-in email and SNMP mechanism or a custom forensic script in AppInternals Xpert to send alerts to the existing system.

Configure alerts in AppResponse Xpert to send SNMP traps to the existing system.

Set up BrowserMetrix to send email alerts to an email gateway.

Add email alerts to the RPM Dashboard settings.

Configure Transaction Trace Warehouse to send email alerts to an email gateway when certain thresholds are met.

Default

AppTransaction Xpert does not filter a trace during import.

None

Use trace explorer first to filter a trace before trying to import it in transaction analyzer.

None. AppTransaction Xpert gathers it with SNMP polling.

The agent collects latency time from the network and sends it to the console.

Server response time (clients)

Several switches are sending mirrored packets to AppResponse Xpert and some are seeing the same IP conversations.

Port mirroring is configured in both directions—ingress and egress—on two or more switch ports.

Virtual local area network (VLAN)-based mirroring is configured and ingress and egress mirroring is configured on a VLAN.

Ttwo or more VLANsare mirroring, and duplicates of packets that enter one of those VLANs and exit via the other are visible.

You are mirroring traffic from more than one database server of a cluster.

Netflow and monitoring port data merged

Netflow and monitoring port data merged, but only if the "merge netflow and monitoring port data" is enabled in the web user interface configuration pages.

Netflow data only

Monitoring port data only

This is not feasible currently.

Recompile or modify the code.

Set the JAVA_TOOL_OPTIONS environment variable to add the argument into the application start up.

We should not instrument applications that use embedded virtual machines.

Changes in jida.config

Enabling monitoring of generic classes with config.package metrics

Changes in the -agentpath parameter

Enabling cross-tier transactions

Managed nodes use the embedded client and synchronize with a common server.

Managed nodes use the embedded NTP client and synchronize with symmetric multiprocessing (SMP).

Managed nodes use their own NTP client.

No specific NTP configuration is needed, as AppInternal Xpert could handle the correct timing by itself.
