Hi folks,
Is there any way to selectively write output from different plugins to different instances of the write_http plugin? I am using the PostCache chain with regex plugin to selectively target to two separate instances of the write_http plugin.

I have validated that writing output from ALL plugins to ALL instances of write_http plugin works.
I also have validated that I can use PostCache chain with regex to selectively pick plugin output to write to ONE instance of the write_http plugin, while allowing all output to go to a completely different write plugin (not write_http).

Whats not working is if I try to set two instances of write_http plugin as target for two PostCache chains or where one is associated and the other is set as default write target. In each of these cases, only one of the two instances works.

Is this by design? Can only one instance of a plugin be associated with a Chain?

Here's my question on StackOverflow with more details:

I setup an influxdb that receives input from several drives on a machine running collectd and it's smart plugin.

I started looking at the influxdb database to see what measurements / series (SMART attributes) showed up...

I narrowed it down to the following for each drive on each host:


I also found a list of Critical SMART attributes on Wikipedia (you can sort them as such), but I'm uncertain of how they relate to what I'm receiving from collectd.

I'd like to be able to detect when a drive is about to go bad, and Wikipedia says that I have about a 50% chance to detecting it if I use such attributes to graph changes in something like grafana.

Unfortunately though, I'm also uncertain of which attributes might be non-sense (on my drives) and which ones are real; and where to find such information... Also there doesn't seem to be much documentation about how the attributes in influxdb relate to those listed in wikipedia...(though I would think it has something to do with the source code for the plugin and the identifier listed in wikipedia)

Hi guys,

Any way to use 2plugins at the same time?
Something like : exec (first plugin)
Pass the output to the second?

Thanks a lot,

Is there a way to programmatically get the Interval specified in collect.conf. I'm using a python plugin to calculate operations per second. Currently, I have 10 hard coded for the calculation since we use the default interval of 10 seconds.

Hi Folks
My Team and I are working on Platform Service Assurance (SA) for NFV deployments and are working on enabling collectd with Telemetry and events/notifications features for NFVI SA. I was wondering if there was a weekly community call or meetup where we could share what we are trying to do and to see if the community agrees with the approaches we are pursuing and the features we are implementing.

collectd 5.7.1 has been released and is available for download. This is a patch release that is only fixing bugs in the 5.7 version and doesn't introduce new features.

I would like to use Collectd in order to gather metrics of UBIFS and UBI MTD. Would you recommend some sort of method that enables to perform such task? Because, there is no built-in plugin for it.
Thank you in advance.

Hello, I have some questions for collectd, If it is not suitable that send the questions at the forum. please pardon me. Sorry for it.

I want to enable write_riemann by configure, but i get the below error message:
write_riemann . . . . no (pkg-config doesn't know libriemann-client)
I had installed collectd-write_riemann, riemann-c-client, protobuf-c. Which packages do i miss?
Please give me some hide. Thanks you very much.

Hello everybody,

Can collectd access the third application and collect business data by the third application?
If yes, can we use which plugins to do it?
Or can collectd timely pull business data from the third application? Thanks you very much.
