At Tembo, we’ve been building a world-class, developer friendly managed Postgres solution in Tembo Cloud. Tembo Cloud allows you to unlock the full power of the Postgres ecosystem with support for over 200 extensions and 10+ workload optimized stacks.

Today, we’re excited to announce that Tembo Cloud now integrates seamlessly with pganalyze - a powerful tool that helps you understand and optimize your Postgres performance. With this integration, you can now easily monitor, analyze your Tembo Cloud Postgres instance with detailed insights into your database performance and configure alerts to receive notifications about the same.

What is pganalyze?

pganalyze helps you deliver consistent database performance through intelligent tuning advisors and continuous database profiling. It provides Postgres configuration recommendations, helps identify slow queries, track query performance over time, and understands the overall health of your database.


pganalyze has a wide range of features that help you understand and optimize your Postgres database. Key features include:

  • Index Advisor
  • EXPLAIN Plans
  • Log Insights
  • System Metrics
  • Alerts and Check-Up

We’ll be talking about some of these features in the following sections.

Connecting your Tembo Instance to pganalyze

Connecting your Tembo Cloud instance to pganalyze is simple and can be done in a few clicks.

Step 1: Sign up for pganalyze

If you don’t already have a pganalyze account, you can sign up for a free trial at

Step 2: Obtain your pganalyze API Key

Once you have signed up for pganalyze, you will need to obtain your pganalyze Collector API Key. You can find or create your API Key in the pganalyze dashboard under the “Settings” section. Copy your Collector API Key to use in the next step.


Step 3: Activate the pganalyze App in Tembo Cloud

To connect your Tembo Cloud instance to pganalyze, you will need to activate the pganalyze App for your instance.


  1. Log in to Tembo Cloud at
  2. Select the instance you want to connect to pganalyze.
  3. Click on the “Apps” tab in the instance details page.
  4. Submit your pganalyze API key in the “API Key” section and click “Activate”.
  5. Click the “pganalyze App” button to access your pganalyze dashboard.

Once activated, pganalyze will start collecting and analyzing your database performance data, and provide you with detailed insights into your database performance. You can access your pganalyze dashboard by clicking on the “pganalyze app” button.

Tuning Advisors

Some of the most useful features in pganalyze are its tuning advisors. The Index Advisor and VACUUM Advisor help you optimize your database performance by providing recommendations for creating and maintaining indexes and optimizing table bloat.

Index Advisor

The pganalyze Index Advisor automatically detects missing indexes and recommends single and multi-column indexes that improve query performance across your databases. These index recommendations are based on your database schema, statistics, and query workload. In addition to recommending new indexes, the Index Advisor also provides insights into existing indexes and why they may actually be ignored. This can be particularly useful for identifying whether a slow query is indexed properly. Read more about the Index Advisor in the pganalyze documentation.


VACUUM Advisor

Optimizing VACUUM is critical for maintaining peak Postgres performance, but it can be a complex and time-consuming task. The VACUUM Advisor provides insights and recommendations based on the following key metrics such as autovacuum efficiency, dead rows, and table bloat. It does this by scanning each table’s statistics and combining them with the Postgres logs to provide you with a holistic view of bloat, freezing and individual tables. To ensure proactive monitoring, pganalyze provides alerts related to these insights. Read more about the VACUUM Advisor in the pganalyze documentation.


Log Insights

pganalyze provides detailed insights into your database logs, including slow queries, errors, and other important events. To make this possible on Tembo Cloud, we’ve made some contributions to the open source pganalyze collector. This allows pganalyze to collect logs from your Tembo Cloud instance and provide you with detailed insights into your database logs.


With Log Insights enabled, we can make use of other powerful features, such as EXPLAIN Plans.


pganalyze simplifies viewing EXPLAIN plans by integrating with the auto_explain extension. It highlights crucial information in query plans, making important data more noticeable. To make this integration as seamless as possible, we automatically modify configs and extensions in your Tembo instance. More details about this feature can be found in the pganalyze documentation.


Alerts and Check-Up

pganalyze also provides powerful alerting and notification features that help you stay on top of your database performance. You can set up custom alerts based on query performance, system metrics, and other important events. pganalyze will notify you when an alert is triggered, so you can take action to resolve any issues.

Alerts can be configured to send notifications via email, Slack, and PagerDuty, so you can stay informed about your Tembo instance no matter where you are.



We’re excited to bring pganalyze to Tembo Cloud, and we’re confident that this integration will help you better understand and optimize your Postgres database. With detailed insights into your database performance, you can make informed decisions to optimize your database performance and improve the overall health of your database.
