How do I configure the ATOP Monitoring and SAR monitoring tools for my EC2 instance running Amazon Linux, RHEL, CentOS, or Ubuntu?

Short description

ATOP and SAR monitoring tools aren't configured on standard Amazon Machine Images (AMIs). You can install these monitoring tools on Amazon Linux, RHEL, CentOS, or Ubuntu Linux-based distributions. Turning on ATOP and SAR monitoring provides a more granular view into the instance's process utilization with a 30-day retention history.

By default, ATOP and SAR monitoring tools collect metrics in 10-minutes intervals. Reconfigure the interval from the default value to 1 minute intervals to collect more granular data.

Resolution

Amazon Linux 2

1. To install the EPEL release package for RHEL 7, use the amazon-linux-extras command:

   sudo amazon-linux-extras install epel

2. Install the monitoring tools:

   sudo yum -y install sysstat atop --enablerepo=epel

3. Change the log collection interval:

   sudo sed -i 's/^LOGINTERVAL=600.*/LOGINTERVAL=60/' /etc/sysconfig/atop
   sudo sed -i -e 's|*/10|*/1|' -e 's|every 10 minutes|every 1 minute|' /etc/cron.d/sysstat

4. Turn on and restart services:

   sudo systemctl enable atop.service crond.service sysstat.service
   sudo systemctl restart atop.service crond.service sysstat.service

Amazon Linux AMI

1. Install the monitoring tools.

   Note: Amazon Linux has the EPEL repository already installed.

   sudo yum -y install sysstat atop --enablerepo=epel
   sudo sed -i 's/^INTERVAL=600.*/INTERVAL=60/' /etc/sysconfig/atop
   sudo sed -i -e 's|*/10|*/1|' -e 's|every 10 minutes|every 1 minute|' /etc/cron.d/sysstat

2. Turn on and restart services:

   for _service in atop crond sysstat; do sudo chkconfig ${_service} on; sudo service ${_service} start; done

RHEL and CentOS

The following configuration steps are the same for each major release of RHEL and CentOS.

2. Install the monitoring tools:

   sudo dnf -y install sysstat atop --enablerepo=epel

3. Change the log collection interval:

   sudo sed -i 's/^LOGINTERVAL=600.*/LOGINTERVAL=60/' /etc/sysconfig/atop
   sudo mkdir -v /etc/systemd/system/sysstat-collect.timer.d/
   sudo bash -c "sed -e 's|every 10 minutes|every 1 minute|g' -e '/^OnCalendar=/ s|/10$|/1|' /usr/lib/systemd/system/sysstat-collect.timer > /etc/systemd/system/sysstat-collect.timer.d/override.conf"
   sudo sed -i 's|^SADC_OPTIONS=.*|SADC_OPTIONS=" -S XALL"|' /etc/sysconfig/sysstat

4. Turn on and restart services:

   sudo systemctl enable atop.service crond.service sysstat.service
   sudo systemctl restart atop.service crond.service sysstat.service

Ubuntu

Ubuntu 20.04

1. Install the monitoring tools:

   sudo apt-get update

2. To change the log collection interval and configure sysstat to report disk and inodes usage, add -S XALL in the configuration file:

   sudo sed -i 's/^LOGINTERVAL=600.*/LOGINTERVAL=60/' /usr/share/atop/atop.daily
   sudo sed -i -e 's|5-55/10|*/1|' -e 's|every 10 minutes|every 1 minute|' -e 's|debian-sa1|debian-sa1 -S XALL|g' /etc/cron.d/sysstat
   sudo bash -c "echo 'SA1_OPTIONS=\"-S XALL\"' >> /etc/default/sysstat"

3. Turn on and restart services:

   sudo sed -i 's|ENABLED="false"|ENABLED="true"|' /etc/default/sysstat
   sudo systemctl enable atop.service cron.service sysstat.service
   sudo systemctl restart atop.service cron.service sysstat.service
