История о том, что старые и надежные утилиты порой нуждаются troubleshooting на новых OS (CentOS 8)

-

 Привет сообщество, 

на связи Гончик Цымжитов. Сегодня, хочу поделиться с короткой историей, о том, как верный инструменты неожиданно ломают на новых ОС, и как легко чинятся.

Итак, все мы знаем, что centos.rip, через очень промежуток времени, поэтому я перехожу везде на Oracle Linux 8. 

Мой любимый инструмент по настройке серверов PostgreSQL, это postgresqltuner.pl, где я уже рассказывал в этой статье. 

Настройка как обычно идет очень просто:

# dnf install -y perl-DBD-Pg
# wget -O postgresqltuner.pl https://postgresqltuner.pl
# chmod +x postgresqltuner.pl

Но в этом, раз когда запускал скрипт встретился с такой проблемой,

# ./postgresqltuner.pl --ssd

Can't locate Memoize.pm in @INC (you may need to install the Memoize module) (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at ./postgresqltuner.pl line 262.

BEGIN failed--compilation aborted at ./postgresqltuner.pl line 262.

Долго искал на просторах интернета решение, так как не нашел делюсь заветной командой которая решает проблему сходу.


# dnf install perl

Далее как обычно запускаем и наслаждаемся.

# ./postgresqltuner.pl  --ssd

Данный совет работает отлично, на RHEL-based OS, таких как CentOS 8, RHEL8 и протестирован на Oracle Linux 8.


Хорошего дня!

С уважением,

Цымжитов Гончик

Overview and practical use cases with open source tracing tool for Java Apps. Glowroot. Installation

In that small article, you can find how to install the agent of Glowroot. Installation of the application is quite simple on agents, and this article shows a scheme for working with a built-in collector, but for industrial installations we use it with a bundle with elasticsearch. The installation can be both for individual nodes and so for the central collector. In this case, consider for a separate node. Prerequisites: {jira_home} - is location of Jira home directory. {jira_installation_directory} is the location of Jira installation directory.   Steps: Downloading the installer wget -c https://github.com/glowroot/glowroot/releases/download/v0.13.6/glowroot-0.13.6-dist.zip To check, create a directory via command   mkdir -p /{jira_home}/glowroot/tmp Let the Jira process write and set ownership for simplicity, but it is recommended that you just give the write ability to the owner of the Jira process. chown -R jira: /{jira_home}/glowroot We additionally set the argument to setenv.sh in

Atlassian Community, let's collaborate and provide stats to vendors about our SQL index usage

  Hi!  Gonchik is in touch. Today I would like to get a little bit of help from you related SQL indexes on your Jira installation (Data Center, Server edition does not matter).    I would like to share a story about  PostgreSQL  and  Jira 8.13.3  ( JSD 4.13.3 )  release.  In that post I will be happy if you answer and comment about your instance indexes, as those info can help to improve the existing situation of heavy indexes.  Typically, it starts from improvement of configuration (e.g. using  https://postgresqltuner.pl/ ),  then query analyzing, adding indexes, after removing as heavy one (shortly  https://wiki.postgresql.org/wiki/Index_Maintenance ) :)    I use like this query in PostgreSQL: SELECT s.schemaname,        s.relname AS tablename,        s.indexrelname AS indexname,        pg_size_pretty(pg_relation_size(s.indexrelid::regclass)) AS index_size,        idx_tup_read,         idx_tup_fetch,         idx_scan FROM pg_catalog.pg_stat_user_indexes s JOIN pg_catalog.pg_index i O

  Hello community, Gonchik Tsymzhitov is in touch. Today, I would like to share with you a short story about postgresqltuner.pl in usage.  So from previous articles I hope you configured the PostgreSQL server and postgresqltuner.pl.  After executing command, ./postgresqltuner.pl --ssd for ssd disks server. You can see like this output: postgresqltuner.pl version 1.0.1 [OK]      I can invoke executables Connecting to /var/run/postgresql:5432 database template1 as user 'postgres'...
