Hi Shadi,

Attachment is not there in your mail. I think mailing list dropped the
attachment. IMHO, we should create a JIRA issue and attach the doc to the
issue so that we can move it to Samza docs.

I have a document with some of the metrics. I had gathered these around
last summer, so they may be out-of-date. I have attached the document to
this email. Hope it can help.

Hi David and Xinyu,

If you want to get the number of messages processed, "process-envelopes"
is
the correct metrics. "process-calls" gives measure the number of times
RunLoop#process method is called. So "process-calls" get updated even
without processing any messages (This happens when no new messages in
input
stream). "process-ns" can be used as the average time taken to process a
message. But this average also includes time taken to process null
messages. So I don't trust the accuracy of that metric.

Each metric emitted by Samza contains a header which includes job name,
job
id, container name and metric timestamp. You can use it to calculate
messages per second values.

If you are using KV store, KeyValueStoreMetrics contains metrics such as
bytes read, bytes write, puts and gets for each store.

Thanks
Milinda

Hi, David,

I didn't find a wiki page that contains the descriptions of all Samza
metrics. You can find the basic metrics by googling the following
classes:
SamzaContainerMetrics, TaskInstanceMetrics, SystemConsumersMetrics and
SystemProducersMetrics. For your example, you can use the
"process-calls"
in SamzaContainerMetrics to get the processed message count, and divide
the
delta by time to get the messages processed per sec. In practice, you
can
either use JConsole to connect to the running Samza container or consume
the MetricsSnapshot topic to get the detailed metrics.

Thanks,
Xinyu

Hi,

Where can I find the detailed descriptions of the out of the box
metrics
provided by MetricsSnapshotReporterFactory and JmxReporterFactory?

I'm interested in seeing the basic metrics of the my samza job (e.g.
messages_processed_per_sec). But it's hard to ping point to the
specific
metric that shows me that.

Thanks,
David
