Bug #: 14755
Summary: Feature Request: Have ability to send data over
network in Flight recorder mode
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: server
AssignedTo: systemtap@sourceware.org
ReportedBy: bugzilla@smetj.net
Classification: Unclassified
Hi,
The motivation for being able to transmit data over network using a simple
network protocol is that it would make life easier to centralize
a large amount of metrics from a large amount of hosts.
It's also not required to foresee any local disk space nor memory to store
data, which could be handy on vm environments with a higher guest density.
I would *personally* find UDP more than sufficient, it would also be less
intrusive or blocking for stap when the remote destination isn't available.
There's a performance gain when writing directly to a socket using proper
buffering compared to redirecting stdout to another process in order to send
stap output over network. This small poc is in Python but should be relevant
nevertheless: https://gist.github.com/3935398
Besides that it's from an sysadmin point of view cleaner to have network
support built in? One less dependency, native support, no wrapper scripts
required.
Thanks,
Jelle
