Multiple, incompatible collection agents
Many times organizations with multiple log analysis tools, each with its own collection agent, will need to deploy multiple collection agents on the same host.
Big data issues
The volume, variety, and velocity of log data generated by large IT environments can overwhelm many lightweight log collection tools.
Complex collection solutions
Multiple collection tools can create data silos which make sharing log data among multiple groups difficult.
Combining log management and analysis functions can prove to be expensive if the solution can’t deliver real value to multiple user groups.
Reliability problems on end-points
Unstable collection agents that frequently crash can cause logs to go missing and cause headaches for IT operations.
