Issue/Introduction
This request relates to running XCOM under AWS EC2 Cloud and using Amazon Auto Scaling Groups (ASG) with FSx file system
Each EC2 host has an XCOM instance which writes to its own individual log file.
Would like to consolidate all XCOM logs into a single shared log file located on FSX, with multiple EC2 XCOM instances writing to it simultaneously.
- Does XCOM support multiple xcom services writing concurrently to a network-mounted singular log file (e.g., on FSx)?
- Are there any known issues or limitations related to file locking, deadlocks, or performance degradation in such a setup?
Environment
XCOM™ Data Transport® for UNIX/Linux 12.0
Resolution
In the short/medium term for the current version of XCOM for Linux 12.0 each XCOM instance can only write to individual log files and a shared log is not possible. XCOM Engineering advised there are several "enhancement" options, but none of them can be done immediately.
One option currently available is to consider using the existing XCOM Splunk (HEC) interface as a common point of logging. XCOM was recently upgraded to add Observe Inc. support into the HEC.
