[[service-overview]]
|
|
=== Service overview
|
|
|
|
Selecting a <<services,*service*>> brings you to the *Service overview*.
|
|
The *Service overview* contains a wide variety of charts and tables that provide
|
|
visibility into how a service performs across your infrastructure.
|
|
|
|

|
|
[[service-latency]]
|
|
=== Latency
|
|
|
|
Response times for the service. You can filter the *Latency* chart to display the average,
|
|
95th, or 99th percentile latency times for the service.

[[service-throughput-transactions]]
|
|
=== Throughput and transactions
|
|
|
|
The *Throughput* chart visualizes the average number of transactions per minute for the selected service.
|
|
|
|
The *Transactions* table displays a list of _transaction groups_ for the
|
|
selected service and includes the latency, traffic, error rate, and the impact for each transaction.
|
|
Transactions that share the same name are grouped, and only one entry is displayed for each group.
|
|
|
|
By default, transaction groups are sorted by _Impact_ to show the most used and slowest endpoints in your
|
|
service. If there is a particular endpoint you are interested in, click *View transactions* to view a
|
|
list of similar transactions on the <<transactions, transactions overview>> page.

[[service-error-rates]]
|
|
=== Error rate and errors
|
|
|
|
The *Error rate* chart displays the average error rates relating to the service, within a specific time range.
|
|
|
|
The *Errors* table provides a high-level view of each error message when it first and last occurred,
|
|
along with the total number of occurrences. This makes it very easy to quickly see which errors affect
|
|
your services and take actions to rectify them. To do so, click *View errors*.

[[service-span-duration]]
|
|
=== Span types average duration and dependencies
|
|
|
|
The *Average duration by span type* chart visualizes each span type's average duration and helps you determine
|
|
which spans could be slowing down transactions. The "app" label displayed under the
|
|
chart indicates that something was happening within the application. This could signal that the
|
|
agent does not have auto-instrumentation for whatever was happening during that time or that the time was spent in the
|
|
application code and not in database or external requests.
|
|
|
|
The *Dependencies* table displays a list of downstream services or external connections relevant
|
|
to the service at the selected time range. The table displays latency, traffic, error rate, and the impact of
|
|
each dependency. By default, dependencies are sorted by _Impact_ to show the most used and the slowest dependency.
|
|
If there is a particular dependency you are interested in, click *View service map* to view the related
|
|
<<service-maps, service map>>.
|
|
|
|
IMPORTANT: A known issue prevents Real User Monitoring (RUM) dependencies from being shown in the
|
|
*Dependencies* table. We are working on a fix for this issue.

[[service-instances]]
|
|
=== All instances
|
|
|
|
The *All instances* table displays a list of all the available service instances within the selected time range.
|
|
Depending on how the service runs, the instance could be a host or a container. The table displays latency, traffic,
|
|
errors, CPU usage, and memory usage for each instance. By default, instances are sorted by _Throughput_.
