The Informix PMDA (for Informix 7) was only ever released for Irix (never ported to Linux) and according to my sparse notes was last updated in about 1994.
At that time, the PMDA used C code to execute direct SQL to interrogate the performance views, and was exposed to variations in the schema for those views between releases ... these days there may be better APIs.
The thing that really killed it was no one in the PCP team had access to a licenced Informix installation for testing.
If you wanted to develop a PMDA, contact me directly at kenj@xxxxxxxxxxxxxxxx and I'll give you such additional information as I'm able.
As a quaint historical note, at that time, PMDAs were also available for Oracle 7 and Sybase 10.
