Python – Get epoch time stamp in milliseconds

To get epoch time stamp in Python we need to time.time() function.
time.time() will returns a float value with double precision counting seconds since epoch and to convert it to milliseconds multiply it with 1000.
With below example code I will show how to get epoch time stamp in milliseconds:
>>> import time
>>> time.time()
>>> int(time.time() * 1000)

In above example int(time.time() * 1000) will return epoch time in milliseconds.

Service design is modular with a logical structure. Approach it as a system and try to improve it as a whole, not just tiny pieces of it. To do that, … … Continue reading →

Phasing out legacy command line options

For historical reasons, rsyslog offers a number of command line options which are actually configuration settings. These stem back to the days of the original syslogd, where the conf file was just a routing table and "all" other configuration was done via the command line. Some of them (e.g. -r to enable listening to the standard UDP port) have already been removed quite a while ago. Now, we are very serious about removing the rest of them.
