Comment personnaliser `show processlist` dans mysql?

Question

Je veux commander dans le temps, mais il semble impossible de le faire?

Les versions les plus récentes de SQL prennent en charge la liste de processus dans information_schema:

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST

Vous pouvez ORDER BY comme bon vous semble.

La table INFORMATION_SCHEMA.PROCESSLIST a été ajoutée dans MySQL 5.1.7. Vous pouvez trouver la version que vous utilisez avec:

SELECT VERSION()

Reza S · Answer

La commande

show full processlist

peut être remplacé par:

SELECT * FROM information_schema.processlist

mais si vous utilisez la dernière version, vous pouvez y ajouter la clause WHERE:

SELECT * FROM information_schema.processlist WHERE `INFO` LIKE 'SELECT %';

Un autre outil utile pour cela à partir de l'interface de ligne de commande est la commande pager.

par exemple

pager grep -v Sleep | more; show full processlist;

Ensuite, vous pouvez parcourir les résultats.

Vous pouvez également rechercher certains utilisateurs, adresses IP ou requêtes avec grep ou sed de cette manière.

La commande de pager est persistante par session.

Vous pouvez simplement capturer la sortie et la transmettre à travers un filtre, par exemple:

mysql show processlist | grep -v '^\+\-\-' | grep -v '^| Id' | sort -n -k12

Les deux greps suppriment les lignes d'en-tête et de fin (d'autres peuvent être nécessaires si d'autres ne contiennent pas d'informations utiles) et le tri est effectué sur la base du champ numérique numéro 12 (je pense que c'est exact).

Celui-ci fonctionne pour votre sortie immédiate:

mysql show processlist | grep -v '^\+\-\-' | grep -v '^| Id' | grep -v '^[0-9][0-9]* rows in set ' | grep -v '^ ' | sort -n -k12

Si vous utilisez une ancienne version de MySQL, vous pouvez toujours utiliser\P combiné avec du code awk de Nice. Exemple intéressant ici

N'est-ce pas exactement ce dont vous avez besoin?

... Nous n'avons pas encore de version plus récente de MySQL, j'ai donc pu le faire (ne fonctionne que sous UNIX):

 Host=maindb echo "show full processlist\G" | mysql -h$Host | grep -B 6 -A 1 Locked

Ce qui précède interroge toutes les sessions verrouillées et renvoie les informations et le code SQL impliqués.

... Donc, en supposant que vous vouliez interroger les sessions en veille:

 Host=maindb echo "show full processlist\G" | mysql -h$Host | grep -B 6 -A 1 Sleep

Ou, en supposant que vous deviez fournir des paramètres de connexion supplémentaires pour MySQL:

 Host=maindb user=me password=mycoolpassword echo "show full processlist\G" | mysql -h$Host -u$user -p$password | grep -B 6 -A 1 Locked

Avec quelques ajustements, je suis sûr qu'un script Shell pourrait être facilement créé pour interroger la liste de processus comme vous le souhaitez.
