List of Monitored Metrics

Below is a complete list of  metrics that are monitored by RightScale's Monitoring System. 

NOTE: The monitoring features are only available for Premium accounts.  If you have a Developer account, you will need to contact sales@rightscale.com to upgrade.

• apache
  Displays graphs for overall bits/sec and requests/sec served by all the httpd processes running on the machine. In addition there are individual graphs showing the number of httpd processes in a specific state: closing, dnslookup, finishing, idle-cleanup, keepalive, logging, open, reading, sending, statring, and waiting. There is also a 'scoreboard' graph that summarizes the state information in a single graph with each state identified by a different color.
  
  
• cpu
  Displays graphs showing the fraction of time cpu 0,1,...,n spends on each state: idle, interrupt, nice, softirq, steal, system, user, and wait. There is also an 'overview' graph that displays all the states in a single graph using different colors. The cpu information displayed by these graphs is similar to that given by unix commands: sar, iostat, or top.
  
  
• df
  Displays graphs showing the file system disk usage. There are graphs for each of the mounted file partitions showing the amount of used and available disk usage relative to the total amount. Each graph shows statistics for the minimum, average, maximum, and last values.
  
  
• disk-xxxx
  Displays graphs showing the performance statistics for the attached hard disks. Individual graphs are: read and written bytes/sec (octets), disk operations/sec, merged operations/sec and time for an I/O operation. The 'merged' operations represent the number of logical operations in the queue that could be merged together so that all operations can be satisfied with a single physical disk access. Each graph shows statistics for the average, maximum, and last values.
  
  
• haproxy
  Displays graphs showing the following information:
  (haproxy_status) the health check status of each instance in each group.

• 2: Active.  The server is active.
  
• 1: Down, going Active.  The server is going to be active.
  
• 0: No check or other. 
  
• -1: Active, going Down.  The server is going down.
  
• -2: Down.  The server is down.
  

(haproxy_traffic)

• Requests per second.
• Response errors per second.
• Health check errors per second.

(haproxy_sessions)

• Current sessions of each instance.
  
• Queued sessions of each instance.

• interface
  Displays graphs showing the network interface activity with respect to errors/sec, octets/sec, and packets/sec for both incoming and outgoing interfaces. Each graph shows statistics for the minimum, average, maximum, and last values.
  
  
• load
  Displays graphs showing the system load as defined by the number of runnable tasks in the run queue. The statistics are running averages over 1, 5, and 15 minutes. Each graph shows statistics for the minimum, average, maximum, and last values.
  
  
• memory
  Displays graphs showing the allocation of memory for used (currently used by programs), free (not in use), buffers (used by Linux to cache access to block devices), and cached (page cache; used to speed up data access). Each graph shows statistics for the minimum, average, maximum, and last values.
  
  
• mysql
  Displays graphs showing internal MySQL activity corresponding to the information given by MySQL when given the 'show status' command. The individual graphs can be grouped into the following catagories: command statistics, handler statistics, query cache statistics, and thread statistics.
  
  
• ping
  Displays graphs showing the network latency between the current instance and machines on the following domains: ec2.amazonaws.com, s3.amazonaws.com, and www.rightscale.com domains. Each graph shows statistics for the minimum, average, maximum, and last values.
  
  
• processes
  Displays graphs showing the number of processes grouped by their state (e.g. blocked, paging, running, sleeping, stopped, or zombie). Each graph shows statistics for the minimum, average, maximum, and last values.
  
  
• processes-xxxx
  Displays graphs showing the number of processes and associated threads for each of the following applications: 'alert', 'collectd', 'cron', 'haproxy', 'httpd.worker', 'merb', 'mongrel_rails', 'mysqld', 'sshd', and'tomcat'. Which ones are displayed depends on the specific value given to parameter MON_PROCESSES. Each graph shows statistics for the minimum, average, maximum, and last values.
  
  
• swap
  Displays graphs showing the amount of swap space that is either cached, free, or used. Each graph shows statistics for the minimum, average, maximum, and last values.
  
  
• users
  Displays a graph showing the number of users connected to the instance. Each graph shows statistics for the minimum, average, maximum, and last values.
