Average disk graph2/2/2024 ![]() It is available for most Linux distributions, but sometimes needs to be installed from repositories. Not used in this example, but -c can report wait IO percentage, which in most cases is related to the CPU waiting for data from the disks. The display is updated every second, but only once per 60 seconds a new line will be started. -D to specify the exact devices to reportĦ0 to average over 60 seconds.system-dsk/total-dsk/sda-dsk/sdb-dsk/sdc-dsk/md1. The File System reports display the amount of disk-space used, in percent. It can show totals and statistics per disk and even md-devices (RAID), also can use colors for better overview: $ dstat -tdD total,sda,sdb,sdc,md1 60 This report displays total virtual memory usage over time, in percent. Some other options that can show disk usage in trending graphs is munin and cacti. Linux 3.5.2-x86_64-linode26 (linode) _x86_64_ (4 CPU)Īvg-cpu: %user %nice %system %iowait %steal %idleĭevice: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util To see current utilization broken out by device, you can use the iostat command, also from the sysstat package: $ iostat -x 1 Using the Debian package, you must enable the stat collector via the /etc/default/sysstat config file after package installation. The %iowait is the time spent waiting on I/O. My personal favorite is the sar command from sysstat. A graph legend appears along with metrics for that specific point in time.For disk I/O trending there are a few options. When you mouse over any of the graphs, a line appears on all of them, pinpointing a moment in time. Data resolution is based on number of points, with a fixed number of points per plot. The Droplet graph timeframe options are 6 hours, 24 hours, 7 days, or 14 days. The Disk Usage line graph shows the percentage of space being used on the Droplet’s disk. The Memory line graph displays the percentage of physical RAM in use. You can find more details on load average in the metrics definitions. There are three lines representing 1-, 5-, and 15-minute load average calculation timeframes in blue, green, and purple, respectively. Load Average measures whether the CPU is keeping up with queued processes. Once the agent is installed, you’ll have access to these additional graphs: You can install the metrics agent automatically when you provision a Droplet or after a Droplet has been created. You can enable additional metrics graphs and alerting with the DigitalOcean metrics agent, which is a small utility that runs on the Droplet. ![]() The default Droplet graphs use metrics collected by external tools they require no additional services on the Droplet itself. Incoming bandwidth use is shown in dark purple and outgoing bandwidth in light purple. The Bandwidth private chart displays the VPC network bandwidth usage in megabits per second. Like the Bandwidth public graph, the Bandwidth private graph does not appear until there is actual network traffic. If you have enabled private networking on the Droplet, you’ll also have access to a fourth graph to track VPC network bandwidth usage. The times in these graphs are in your local time zone, as determined by your browser. The Disk I/O displays disk read and write operations in megabytes per second, with read operations in dark green and write operations in light green. The CPU usage shows the percent of total processing power being used, with light blue for user jobs and dark blue for system processes. Incoming bandwidth is dark purple and outgoing bandwidth is light purple. The Bandwidth public chart displays public bandwidth usage in megabits per second. By default, three graphs are available for any Droplet: You’ll arrive directly on the Graphs page. To view a Droplet’s graphs, click its name on the dashboard. ![]() H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \ ![]() To obtain CPU metrics for a Droplet with cURL, call:
