asprom's Issues

aerospike_node_up 0

Hi!

Thanks for this great tool!

I'm having some issues getting the exporter working. I'm using the 1.8.0 binary. What versions of Aerospike are compatible? I'm using community edition 3.6.3.

It looks like the node is not up?

dashboard

Hi!
Thnx for aerospike exporter, good job!
Could you please share your grafana dashboard in json format?

latency: missing measurements line

2017/10/13 16:16:27 starting asprom. listening on :9145
2017/10/13 16:16:32 latency: missing measurements line
2017/10/13 16:16:47 latency: missing measurements line

I suspect this is because we have authentication enabled. Is there any work around?

thanks

"Missing" statistics

Hey,

Since you've been so nice :-D
Any reason why you limited yourself to these metrics instead of grabbing all of them?

I am thinking specifically to 1 that is missing that we could use (but there are probably more), and that's master_objects and non_replica_objects (alongside replication-factor and effective_replication_factor).

Security?

Hi,
This doesn't have support for a user/password/credentials file?
People really run their cluster without security enabled?

Thanks :-)

relationship to asgraphite

@alicebob hi Harmen, I opened an issue over at the asgraphite repository about missing metrics. I had assumed that the metrics were missing due to missing implementation in the asgraphite library ... but now I am wondering if I misinterpreted the phrase "follows the logic from asgraphite" in the (asprom README)[https://github.com/alicebob/asprom/blob/master/README.md].

Is this library a reimplementation of asgraphite functionality, or does it "wrap" the asgraphite library? If the former, it appears I would be better off creating the asgraphite issue here instead of over there.

Added TLS support configuration

Hi alicebob,
I have added a TLS support to the tool.
I changed the flags a bit and basically added an option to choose either secure connection or not.
Would love to contribute back, wdyt?

Latency metrics for batch reads?

Hey,

I tried to read the latency.go code but am a bit lost.
In one of our namespaces, we mostly do batch reads. You don't include these in things like aerospike_ops_read (we add aerospike_ns_batch_sub_read_success to it currently), and I don't see latency metrics (like aerospike_latency_read) at all.

I was wondering if:

  • metrics existed at all for the batch latencies etc.?

  • can we either include them with the regular metrics, or create 2 new set of metrics:
    1 for batch read/writes
    1 for regular read/writes (already exist)
    1 that's an aggregated view of the 2

That last one is useful because for instance right now we have:

sum(aerospike_ops_read) by (namespace) + sum(irate(aerospike_ns_batch_sub_read_success[5m])) by (namespace)

One of the problems is that for instance, on one of our namespace, we have literally 0 regular reads. We only do batch reads. Which means that the first gauge doesn't exist (until someone does a manual read on the cluster). And the sum of "undefined" + 3 is... "undefined" in prometheus.

Let me know if I can help with anything :-)

Thanks!

segfault

We're seeing asprom crashing on a regular basis.
When you have time to look into it :-)

Provision to pass credential via environment variables

Currently asprom takes the aerospike user credential as command line arguments. This allows other users to figure out the credentials by issuing a simple 'ps' command.
Please provide a option to provide credentials via environment variables.
