Hi all,
I am using ceilometer with arithmetic transformer to combine two meters.
Here is an extract of my pipeline.yaml (it's just a dummy test)
sources:
- name: disk_source
interval: 600
meters:
- "disk.read.bytes"
- "disk.read.requests"
- "disk.write.bytes"
- "disk.write.requests"
sinks:
- disk_sink
- disk_read_write_sink
sinks:
- name: disk_read_write_sink
transformers:
- name: "arithmetic"
parameters:
target:
name: "disk.read.write.bytes"
unit: "B"
type: "cumulative"
expr: "2*$(disk.read.bytes) + 2*$(disk.write.bytes)"
publishers:
- rpc://
I get this error:
"Unable to perform calculation, not all of {_disk_write_bytes_ESC,
_disk_read_bytes_ESC} are present"
Anyone using this transformer?
Thanks!
Claudio
