Hello, I have a mongodb replica set with one master node and two slave nodes. I want to install mongodb exoprter to collect mongodb indicators and configure it to send data to existing Prometheus. Do I only need to install mongodb exoprter on the master node of mongodb? Or do I need to install mongodb exoprter on every node? Currently I only have mongodb exopter installed on the master node, but I can’t get information on the two slave nodes ---

Hi Liu, Please install the exporter on each node. ---

Thank you !! That is to say, I should deploy Mongodb\_exporter on all three nodes, and in this way, the MongoDB\_ReplSet\_Summary and MongoDB\_Instances\_Overview dashboards can display information about the three nodes?

If dashboards would be used without a PMM please convert them by the next script. > ---

Hi，I have completed the deployment of three exporters. How do I set the label of target in Prometheus? Will this label affect the display of dashboard ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/c/ce772ff90b99afa762ae5a7254f22eafec549a35.png) ---

The script is replacing PMM2 labels by default Prometheus labels. So no additional labels are required. ---

It worked, but there was another problem. How to obtain the PMM-Pt-summary-Panel plugin? ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/e/e503914ec2493f9af6132df04000c0ef7dc9ca2c.png) ---

It’s a part of PMM2. So please just remove this element from the dashboard. ---

No matter which node I select in mongoDB Replset, this panel shows Primary. I checked that metrics all returned 1. Do you know why? The last image shows details of mongoDB Replset. ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/3/35763d5cec44426a36272dc0219959a2c115e928.png) ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/6/6caecdbf28b4a5bc585e18bf5998704a9eed0ad0.png) ![mongo图片](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/c/ccaf75c7df5dc8ae1d061f31bd10ab14e5f4fe26.png)
