নোট
- v0.10.0 adopts the OpenTelemetry semantic convention names
rpc.client.call.durationandrpc.server.call.duration. The corresponding Prometheus metric names include_call_as shown in the table. - Starting with v0.12.1, server-side Redis and Memcached measurements use
db.server.operation.durationinstead ofdb.client.operation.duration. Update dashboards and alerts that query those server-side measurements.
The .NET processor-count and heap-size instruments use UpDownCounters in OTLP and gauges in Prometheus.
OBI can also export Span metrics and Service graph metrics, which you can enable via the features configuration option.
Starting with v0.14.0, the application feature includes the HTTP body-size
histograms. Use application_red instead if you only want RED metrics, or
combine application_red and application_sizes in the same feature list. See
metrics export features.
HTTP duration and body-size metrics now include error.type on failed requests
by default. Their Prometheus series have an error_type label, with an empty
value for successful requests. Update dashboards and alerts that match the old
series. OTLP span metrics no longer put host.id on each data point; it remains
on the resource and in target_info. OBI’s Prometheus exporter is unaffected.
Starting with v0.15.2, database duration metrics include db.collection.name by
default. RPC client duration includes server.port, and failed RPC server
duration includes error.type. Messaging duration metrics can also split by
operation type and subscription name. MQTT SUBSCRIBE uses a subscription name
instead of a destination name. Review these dimensions when estimating
cardinality or updating existing queries.
The new ring-buffer counters in Internal metrics are also
available through OTLP as obi.bpf.ringbuf.writes and
obi.bpf.ringbuf.write.failures.
Attributes of OBI metrics
For the sake of brevity, the metrics and attributes in this list use the OTel
dot.notation. When using the Prometheus exporter, the metrics use
underscore_notation.
In order to configure which attributes to show or which attributes to hide,
check the attributes->select section in the
configuration documentation.

নোট
The obi.network.inter.zone.bytes metric supports the same set of attributes
as obi.network.flow.bytes, but all of them are hidden by default, except
k8s.cluster.name, src.zone and dst.zone.
The obi.network.flow.packets metric supports the same attributes and
defaults as obi.network.flow.bytes. JVM memory metrics include
jvm.memory.type and jvm.memory.pool.name. The nodejs.eventloop.time
metric includes nodejs.eventloop.state, with a value of idle or active.
Internal metrics
সতর্কতা
OBI v0.12.1 removes Prometheus-style suffixes from four internal OTLP metric
names. Update OTLP queries from obi.bpf.map.entries_total to
obi.bpf.map.entries, from obi.bpf.map.max_entries_total to
obi.bpf.map.max_entries, from obi.bpf.network.packets.total to
obi.bpf.network.packets, and from obi.bpf.network.ignored.packets.total to
obi.bpf.network.ignored.packets. The corresponding Prometheus counter names
remain unchanged. The Prometheus gauge names become obi_bpf_map_entries and
obi_bpf_map_max_entries.
OBI can be configured to report internal metrics in Prometheus Format.
