Running PMM Server Using AWS Marketplace

You can run an instance of PMM Server hosted at AWS Marketplace. This method replaces the outdated method where you would have to accessing an AMI (Amazon Machine Image) by using its ID, different for each region.

../_images/aws-marketplace.pmm.home-page.1.png

Assuming that you have an AWS (Amazon Web Services) account, locate Percona Monitoring and Management Server in AWS Marketplace.

The Pricing Information section allows to select your region and choose an instance type in the table that shows the pricing for the software and infrastructure hosted in the region you have selected (the recommended EC2 instance type is preselected for you). Note that actual choice will be done later, and this table serves the information purposes, to plan costs.

As soon as you select your region, you can choose the EC2 instance in it and see its price. PMM comes for no cost, you may only need to pay for the infrastructure provided by Amazon.

../_images/aws-marketplace.pmm.home-page.2.png

Note

Disk space consumed by PMM Server depends on the number of hosts under monitoring. Each environment will be unique, however consider modeling your data consumption based on PMM Demo web site, which consumes ~230MB/host/day, or ~6.9GB/host at the default 30 day retention period. See this blog post for more details.

  • Clicking the Continue to Subscribe button will proceed to the terms and conditions page.
  • Clicking Continue to Configuration there will bring a new page to start setting up your instance. You will be able to re-check the PMM Server version and the region. When done, continue to the launch options by clicking Continue to Launch.

Select the previously chosen instance type from the EC2 Instance Type drop-down menu. Also chose the launch option. Available launch options in the Chose Action drop-down menu include Launch from Website and Launch through EC2. The first one is a quick way to make your instance ready. For more control, use the Manual Launch through EC2 option.

Setting Up a PMM Instance Using the website GUI

Choose Launch from Website option, your region, and the EC2 instance type on the launch options page. On the previous screenshot, we use the US East (N. Virginia) region and the EC2 Instance Type named t2.medium. To reduce cost, you need to choose the region closest to your location.

Setting up a VPC and an EC2 Instance Type

In this demonstration, we use the VPC (virtual private cloud) named vpc-484bb12f. The exact name of VPC may be different from the example discussed here.

../_images/aws-marketplace.pmm.launch-on-ec2.1-click-launch.1.png

Instead of a VPC (virtual private cloud) you may choose the EC2 Classic (no VPC) option and use a public cloud.

Selecting a subnet, you effectively choose an availability zone in the selected region. We recommend that you choose the availability zone where your RDS is located.

Note that the cost estimation is automatically updated based on your choice.

Limiting Access to the instance: security group and a key pair

In the Security Group section, which acts like a firewall, you may use the preselected option Create new based on seller settings to create a security group with recommended settings. In the Key Pair select an already set up EC2 key pair to limit access to your instance.

../_images/aws-marketplace.pmm.launch-on-ec2.1-click-launch.3.png

Note

It is important that the security group allow communication via the the following ports: 22, 80, and 443. PMM should also be able to access port 3306 on the RDS that uses the instance.

Applying settings

Scroll up to the top of the page to view your settings. Then, click the Launch with 1 click button to continue and adjust your settings in the EC2 console.

Your instance settings are summarized in a special area. Click the Launch with 1 click button to continue.

../_images/aws-marketplace.pmm.launch-on-ec2.1-click-launch.3.png

Note

The Launch with 1 click button may alternatively be titled as Accept Software Terms & Launch with 1-Click.

Adjusting instance settings in the EC2 Console

Your clicking the Launch with 1 click button, deploys your instance. To continue setting up your instance, run the EC2 console. It is available as a link at the top of the page that opens after you click the Launch with 1 click button.

Your instance appears in the EC2 console in a table that lists all instances available to you. When a new instance is only created, it has no name. Make sure that you give it a name to distinguish from other instances managed via the EC2 console.

Running the instance

After you add your new instance it will take some time to initialize it. When the AWS console reports that the instance is now in a running state, you many continue with configuration of PMM Server.

Note

When started the next time after rebooting, your instance may acquire another IP address. You may choose to set up an elastic IP to avoid this problem.

With your instance selected, open its IP address in a web browser. The IP address appears in the IPv4 Public IP column or as value of the Public IP field at the top of the Properties panel.

../_images/aws-marketplace.pmm.ec2.properties.png

To run the instance, copy and paste its public IP address to the location bar of your browser. In the Percona Monitoring and Management welcome page that opens, enter the instance ID.

../_images/installation-wizard.ami.instance-id-verification.png

You can copy the instance ID from the Properties panel of your instance, select the Description tab back in the EC2 console. Click the Copy button next to the Instance ID field. This button appears as soon as you hover the cursor of your mouse over the ID.

Hover the cursor over the instance ID for the Copy button to appear.

../_images/aws-marketplace.pmm.ec2.properties.instance-id.png

Paste the instance in the Instance ID field of the Percona Monitoring and Management welcome page and click Submit.

PMM Server provides user access control, and therefore you will need user credentials to access it:

../_images/PMM_Login.jpg

The default user name is admin, and the default password is admin also. You will be proposed to change the default password at login if you didn’t it.

The PMM Server is now ready and the home page opens.

../_images/PMM_Home_Dashboard.jpg

You are creating a username and password that will be used for two purposes:

  1. authentication as a user to PMM - this will be the credentials you need in order to log in to PMM.

  2. authentication between PMM Server and PMM Clients - you will re-use these credentials when configuring pmm-client for the first time on a server, for example:

    Run this command as root or by using the sudo command

    pmm-admin config --server-insecure-tls --server-url=https://admin:admin@<IP Address>:443
    

Note

Accessing the instance by using an SSH client.

For instructions about how to access your instances by using an SSH client, see Connecting to Your Linux Instance Using SSH

Make sure to replace the user name ec2-user used in this document with admin.

Resizing the EBS Volume

Your AWS instance comes with a predefined size which can become a limitation. To make more disk space available to your instance, you need to increase the size of the EBS volume as needed and then your instance will reconfigure itself to use the new size.

The procedure of resizing EBS volumes is described in the Amazon documentation: Modifying the Size, IOPS, or Type of an EBS Volume on Linux.

After the EBS volume is updated, PMM Server instance will autodetect changes in approximately 5 minutes or less and will reconfigure itself for the updated conditions.

Upgrading PMM Server on AWS

Upgrading EC2 instance class

Upgrading to a larger EC2 instance class is supported by PMM provided you follow the instructions from the AWS manual. The PMM AMI image uses a distinct EBS volume for the PMM data volume which permits independent resize of the EC2 instance without impacting the EBS volume.

Expanding the PMM Data EBS Volume

The PMM data volume is mounted as an XFS formatted volume on top of an LVM volume. There are two ways to increase this volume size:

  1. Add a new disk via EC2 console or API, and expand the LVM volume to include the new disk volume.
  2. Expand existing EBS volume and grow the LVM volume.

Expand existing EBS volume

To expand the existing EBS volume in order to increase capacity, the following steps should be followed.

  1. Expand the disk from AWS Console/CLI to the desired capacity.

  2. Login to the PMM EC2 instance and verify that the disk capacity has increased. For example, if you have expanded disk from 16G to 32G, dmesg output should look like below:

    [  535.994494] xvdb: detected capacity change from 17179869184 to 34359738368
    
  3. You can check information about volume groups and logical volumes with the vgs and lvs commands:

    vgs
    
    VG     #PV #LV #SN Attr   VSize  VFree
    DataVG   1   2   0 wz--n- <16.00g    0
    
    lvs
    
    LV       VG     Attr       LSize   Pool Origin Data%  Meta% Move Log Cpy%Sync Convert
    DataLV   DataVG Vwi-aotz-- <12.80g ThinPool        1.74
    ThinPool DataVG twi-aotz--  15.96g 1.39  1.29
    
  4. Now we can use the lsblk command to see that our disk size has been identified by the kernel correctly, but LVM2 is not yet aware of the new size. We can use pvresize to make sure the PV device reflects the new size. Once pvresize is executed, we can see that the VG has the new free space available.

    lsblk | grep xvdb
    
    xvdb                      202:16 0 32G 0 disk
    
    pvscan
    
    PV /dev/xvdb   VG DataVG    lvm2 [<16.00 GiB / 0    free]
    Total: 1 [<16.00 GiB] / in use: 1 [<16.00 GiB] / in no VG: 0 [0   ]
    
    pvresize /dev/xvdb
    
    Physical volume "/dev/xvdb" changed
    1 physical volume(s) resized / 0 physical volume(s) not resized
    
    pvs
    
    PV         VG     Fmt  Attr PSize   PFree
    /dev/xvdb  DataVG lvm2 a--  <32.00g 16.00g
    
  5. We then extend our logical volume. Since the PMM image uses thin provisioning, we need to extend both the pool and the volume:

    lvs
    
    LV       VG     Attr       LSize   Pool    Origin Data%  Meta% Move Log Cpy%Sync Convert
    DataLV   DataVG Vwi-aotz-- <12.80g ThinPool        1.77
    ThinPool DataVG twi-aotz--  15.96g                 1.42   1.32
    
    lvextend /dev/mapper/DataVG-ThinPool -l 100%VG
    
    Size of logical volume DataVG/ThinPool_tdata changed from 16.00 GiB (4096 extents) to 31.96 GiB (8183 extents).
    Logical volume DataVG/ThinPool_tdata successfully resized.
    
    lvs
    
    LV       VG     Attr       LSize   Pool    Origin Data%  Meta% Move Log Cpy%Sync Convert
    DataLV   DataVG Vwi-aotz-- <12.80g ThinPool        1.77
    ThinPool DataVG twi-aotz--  31.96g                 0.71   1.71
    
  6. Once the pool and volumes have been extended, we need to now extend the thin volume to consume the newly available space. In this example we’ve grown available space to almost 32GB, and already consumed 12GB, so we’re extending an additional 19GB:

    lvs
    
    LV       VG     Attr       LSize   Pool    Origin Data%  Meta% Move Log Cpy%Sync Convert
    DataLV   DataVG Vwi-aotz-- <12.80g ThinPool        1.77
    ThinPool DataVG twi-aotz--  31.96g                 0.71   1.71
    
    lvextend /dev/mapper/DataVG-DataLV -L +19G
    
    Size of logical volume DataVG/DataLV changed from <12.80 GiB (3276 extents) to <31.80 GiB (8140 extents).
    Logical volume DataVG/DataLV successfully resized.
    
    lvs
    
    LV       VG     Attr       LSize   Pool    Origin Data%  Meta% Move Log Cpy%Sync Convert
    DataLV   DataVG Vwi-aotz-- <31.80g ThinPool        0.71
    ThinPool DataVG twi-aotz--  31.96g                 0.71   1.71
    
  7. We then expand the XFS filesystem to reflect the new size using xfs_growfs, and confirm the filesystem is accurate using the df command.

    df -h /srv
    
    Filesystem                  Size Used Avail Use% Mounted on
    /dev/mapper/DataVG-DataLV    13G 249M   13G   2% /srv
    
    xfs_growfs /srv
    
    meta-data=/dev/mapper/DataVG-DataLV isize=512    agcount=103, agsize=32752 blks
             =                          sectsz=512   attr=2, projid32bit=1
             =                          crc=1        finobt=0 spinodes=0
    data     =                          bsize=4096   blocks=3354624, imaxpct=25
             =                          sunit=16     swidth=16 blks
    naming   =version 2                 bsize=4096   ascii-ci=0 ftype=1
    log      =internal                  bsize=4096   blocks=768, version=2
             =                          sectsz=512   sunit=16 blks, lazy-count=1
    realtime =none                      extsz=4096   blocks=0, rtextents=0
    data blocks changed from 3354624 to 8335360
    
    df -h /srv
    
    Filesystem                 Size Used Avail Use% Mounted on
    /dev/mapper/DataVG-DataLV   32G 254M   32G   1% /srv
