Yes, you are right.
There are two files
-rw-r--r-- 1 mysite mysite 2207 Jul 4 2014 /omd/sites/mysite/local/share/check_mk/web/plugins/perfometer/active_checks.py
-rw-r--r-- 1 mysite mysite 30405 Jul 4 2014 /omd/sites/mysite/local/share/check_mk/web/plugins/perfometer/check_mk.py
The first one contains references to check_http:
def perfometer_check_http(row, check_command, perfdata):
time_ms = float(perfdata[0][1]) * 1000.0
return "%.1f ms" % time_ms, \
perfometer_logarithmic(time_ms, 1000, 10, "#66ccff")
perfometers["check-http"] = perfometer_check_http
perfometers["check_http"] = perfometer_check_http
perfometers["check_mk_active-http"] = perfometer_check_http
I did not remember to have put them there. Are they from old releases?
Should they be removed?
