My system is configured to use fr_FR.UTF-8 locale by default.

yann@localhost ~]$ locale
LANG=fr_FR.UTF-8
LC_CTYPE="fr_FR.UTF-8"
LC_NUMERIC="fr_FR.UTF-8"
LC_TIME="fr_FR.UTF-8"
LC_COLLATE="fr_FR.UTF-8"
LC_MONETARY="fr_FR.UTF-8"
LC_MESSAGES="fr_FR.UTF-8"
LC_PAPER="fr_FR.UTF-8"
LC_NAME="fr_FR.UTF-8"
LC_ADDRESS="fr_FR.UTF-8"
LC_TELEPHONE="fr_FR.UTF-8"
LC_MEASUREMENT="fr_FR.UTF-8"
LC_IDENTIFICATION="fr_FR.UTF-8"
LC_ALL=


On mageia 6 and 7, the ping.pl script provided by cacti works well:
[yann@localhost ~]$ perl /var/www/html/cacti/scripts/ping.pl localhost
0.059

But on mageia 8, it didn’t and always return U:
[yann@localhost ~]$ perl /var/www/html/cacti/scripts/ping.pl localhost
U

If I force the locale with LC_ALL=C in the bash CLI, script is working well:
[yann@localhost ~]$ LC_ALL=C perl /var/www/html/cacti/scripts/ping.pl localhost
0.031

It is like the line "$ENV{LANG}='en_US.UTF-8';" in the script is not taken into account.


For understand the issue, I made some modifications in ping.pl script…
Replace the line:
open(PROCESS, "$pingcmd 2>&1 | grep -E '(icmp_[s|r]eq.*time|unknown host|Unknown host|not supported|Name or service not known|No address associated with name)' 2>/dev/null |");

By the line:
open(PROCESS, "$pingcmd 2>&1 | grep -E '(icmp_[s|r]eq|unknown host|Unknown host|not supported|Name or service not known|No address associated with name)' 2>/dev/null |");

And just after line:
chomp($ping);

Add the line:
print "Test:".$ping."\n";


Then there is the new results:
[yann@localhost ~]$ LC_ALL=C perl /var/www/html/cacti/scripts/ping.pl localhost
Test:64 bytes from localhost (::1): icmp_seq=1 ttl=64 time=0.058 ms
0.058[yann@localhost ~]$ 
[yann@localhost ~]$ 
[yann@localhost ~]$ perl /var/www/html/cacti/scripts/ping.pl localhost
Test:64 octets de localhost (::1) : icmp_seq=1 ttl=64 temps=0.042 ms
U

In the second case, it is interesting to note this is "temps" and not "time" that is used in the result. And it explains why script always failed.

For me, this is a regression in Mageia 8.
