pgpro_stats support

By default mamonsu uses pg_stat_statements and pg_wait_samplings in plugins Statements and Wait Sampling. These extensions need to be installed additionally via shared_preload_libraries. But if mamonsu detects PostgresPro instead of vanilla PostgreSQL, it switched automatically to pgpro_stats for both plugins. This is more convenient because pgpro_stats is going by default with PostgresPro.

agent.conf permissions

Now by default mamonsu sets for agent.conf the following permissions:

permissions  user    group
-rw-------   mamonsu mamonsu  jun 16 12:21 agent.conf

new report feature

With other PostgreSQL stats, report now evaluates information about current locks:

$ mamonsu report --run-system --run-postgres -U mamonsu
<...>
# CURRENT LOCKS ##################################
blocked_pid     database          blocked_user  blocking_pid    blocking_user   blocked_statement                                     duration
49934           mamonsu_test_db   postgres      91741           postgres        update mamonsu_logs set value = 0 where value = 3;    0:00:35.199513

NOTE: objects new names

Pay attention to new Zabbix template object names. All mamonsu objects have been unified in template representation, so you should update the template carefully. For example, PostgreSQL: number of user total connections switched to PostgreSQL Connections: Number of Total User Connections. All changes are shown in documentation.
