Hi.

I resolve this SSL handshake issue. It needs to compile NRPE both in server and client side

Great. How are the new payload sizes working out for you?

Hi abrist,

Thank your reply me so many questions.
I try to set define MAX_INPUT_BUFFER 16384 / 65536. The maximum characters are around 6000.
I think now the limitation is in SQL DB side. I think this value is acceptable but may be challenge by other team.

Hi abrist / jolson,

But I don't have skill how to compile nrpe in AIX 5.3 / 6.1 and Soarlis 10 version. what package need to install for compile NRPE

In nagiosxi side, MAX_INPUT_BUFFER 65535.

Hi abrist / jolson,

After I demo /var/log/messages can display to 6000 character in nagios to others team. Their comment is want to show more and more log.

I execute check_nrpe -H 172.31.8.198 -c check_logfiles in nagiosxi. It can display more then 10000 character. Therefore, I think this is limited in DB side.

Could you help to provide the command to set this log field can store 65535 character.

Some client can more then 1 log services. Does this apply to all service log fields?

Try running the following to update the column sizes:

Code: Select all

echo "alter table nagios.nagios_servicestatus modify output varchar(50000);" | mysql -pnagiosxi
echo "alter table nagios.nagios_servicestatus modify long_output varchar(50000);" | mysql -pnagiosxi
echo "alter table nagios.nagios_servicestatus modify perfdata varchar(50000);" | mysql -pnagiosxi
echo "desc nagios.nagios_servicestatus" | mysql -t -pnagiosxi | grep "output\|perfdata"
This will make the service and host list pages in XI look very . . . funky.

Hi abrist,

After apply your command and reboot nagios.

Code: Select all

[root@nagiosxi ~]# echo "alter table nagios.nagios_servicestatus modify output varchar(50000);" | mysql -pnagiosxi
echo "alter table nagios.nagios_servicestatus modify long_output varchar(50000);" | mysql -pnagiosxi
echo "alter table nagios.nagios_servicestatus modify perfdata varchar(50000);" | mysql -pnagiosxi
echo "desc nagios.nagios_servicestatus" | mysql -t -pnagiosxi | grep "output\|perfdata"[root@nagiosxi ~]# echo "alter table nagios.nagios_servicestatus modify long_output varchar(50000);" | mysql -pnagiosxi
[root@nagiosxi ~]# echo "alter table nagios.nagios_servicestatus modify perfdata varchar(50000);" | mysql -pnagiosxi
[root@nagiosxi ~]# echo "desc nagios.nagios_servicestatus" | mysql -t -pnagiosxi | grep "output\|perfdata"
| output                        | mediumtext   | YES  |     | NULL                |                |
| long_output                   | mediumtext   | YES  |     | NULL                |                |
| perfdata                      | mediumtext   | YES  |     | NULL                |                |
[root@nagiosxi ~]#
But it is not work. I generate 13 error messages. In nagios web, it shows 13th and 1 - 9th messages. 10 - 12th messages are missing

In nagios server, I run the command check_nrpe -H 172.31.8.198 -c check_logfiles manually. It can get all messages.

Code: Select all

[root@nagiosxi libexec]# ./check_nrpe -H 172.31.8.198 -c check_logfiles
