+## PostgreSQL Dashboard & Alerts
+
+使用[categraf](https://github.com/flashcatcloud/categraf)中[inputs.postgresql](https://github.com/flashcatcloud/categraf/tree/main/inputs/postgresql)插件采集[PostgreSQL](https://www.postgresql.org/)服务监控指标数据；
+
+### 配置文件示例：
+
+如果是多个PostgreSQL，可以写多个[[instance]]配置
+
+```toml
+[[instances]]
+address = "host=192.168.11.181 port=5432 user=postgres password=123456789 sslmode=disable"
+## specify address via a url matching:
+##   postgres://[pqgotest[:password]]@localhost[/dbname]?sslmode=[disable|verify-ca|verify-full]
+## or a simple string:
+##   host=localhost user=pqgotest password=... sslmode=... dbname=app_production
+##
+## All connection parameters are optional.
+##
+## Without the dbname parameter, the driver will default to a database
+## with the same name as the user. This dbname is just for instantiating a
+## connection with the server and doesn't restrict the databases we are trying
+## to grab metrics for.
+##
+# address = "host=localhost user=postgres sslmode=disable"
+
+## A custom name for the database that will be used as the "server" tag in the
+## measurement output. If not specified, a default one generated from
+## the connection address is used.
+# outputaddress = "db01"
+
+## connection configuration.
+## maxlifetime - specify the maximum lifetime of a connection.
+## default is forever (0s)
+# max_lifetime = "0s"
+
+## A  list of databases to explicitly ignore.  If not specified, metrics for all
+## databases are gathered.  Do NOT use with the 'databases' option.
+# ignored_databases = ["postgres", "template0", "template1"]
+
+## A list of databases to pull metrics about. If not specified, metrics for all
+## databases are gathered.  Do NOT use with the 'ignored_databases' option.
+# databases = ["app_production", "testing"]
+
+## Whether to use prepared statements when connecting to the database.
+## This should be set to false when connecting through a PgBouncer instance
+## with pool_mode set to transaction.
+#prepared_statements = true
+# [[instances.metrics]]
+# mesurement = "sessions"
+# label_fields = [ "status", "type" ]
+# metric_fields = [ "value" ]
+# timeout = "3s"
+# request = '''
+# SELECT status, type, COUNT(*) as value FROM v$session GROUP BY status, type
+# '''
