Hi there,
I'am wondering if there is some documentation about Netdot::Client::REST
which describes how I could trigger the automatic SNMP discovery when
creating new device objects?
Any hints highly appreciated!
bests,
Christian

Bug #1904: Cannot start apache2 with Netdot::Mason

Resolution:
Followed the installation instruction up to the point of linking
/etc/apache2/conf-enabled/netdot.conf.
Apache2 version is Apache/2.4.18 running on Ubuntu 16.04
Other versions are mod_apreq2-20090110/2.8.0 mod_perl/2.0.9 Perl/v5.22.1
The 'service apache2 restart' will be failed with the following error:
# systemctl status apache2.service
??? apache2.service - LSB: Apache2 web server
Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)

The problem has been trimmed down that it stops when it calls the 'use
Netdot::Mason;' in the netdot.conf
Anyway to solve this problem?
The make testdeps is fine as follows:

Carlos and other devs,
There seems to be a couple issues that may be buried deep with respect
to Netdot. I'm wondering if it would be alleviated by leaving mod_perl
and moving to a FastCGI + PSGI solution.
I know that proposal isn't free, but wondering if it would be worth
migrating towards it.
Here are a few of the issues that we experience that may be related to
the mod_perl solution:
- We're hitting a cache issue every once in a while - and it makes
Netdot throw stack traces when trying to create new ipblocks. I've
traced it to the data in the datacache table not accurately
representing the rest of the database. The cached Patricia tree is
incorrect and causes parent ipblock info wrong and then database
insert fails.
- Perhaps related to the above, there are database misses when
creating/updating an ipblock/dns and then immediately searching for
those changed values - Netdot doesn't find the records, but searching
for the preceding name works.
- I cannot enable mod-shib with the apache 2.4 configs for Netdot.
I've searched the mailing lists and have seen DB inconsistency mentioned before.
Just trying to get some dialogue going among the group about these issues.
Thanks!
