For more information, see Networking Metrics.ģThe Block Volume service provides more metrics (in the oci_blockstore metric namespace) for each volume attached to the instance. Expressed as bytes transmitted.ġThis metric is a cumulative counter that shows monotonically increasing behavior for each session of the Oracle Cloud Agent software, resetting when the operating system is restarted.ĢThe Networking service provides more metrics (in the oci_vcn metric namespace) for each VNIC on the instance. Number of times page reclaim was called directly. Expressed as writes per interval.Īverage system load calculated over a 1-minute period. With this tool, you can view whether devices are classified as Up, Critical, Warning, or Undefined. Five-nines availability, however, is difficult to achieve. An uptime of 99.999high availabilityallows for 5.25 minutes of downtime in a single year. The formula for calculating the percentage of uptime, as stated above, is simply uptime divided by total time.
Expressed as reads per interval.Īctivity level from I/O writes. SolarWinds Network Performance Monitor (FREE TRIAL) Although it doesn’t cover websites, SolarWinds Network Performance Monitor is an excellent tool for uptime monitoring on network devices. In its most basic form, uptime is the downtime subtracted from the total time. Expressed as bytes written per interval.Īctivity level from I/O reads. Expressed as a percentage of total time.įor instance pools, the value is averaged across all instances in the pool. shape The shape of the instance.Īctivity level from CPU. resourceDisplayName The friendly name of the instance. region The region where the instance resides. instancePoolId The instance pool that the instance belongs to. imageId The OCID of the image for the instance. faultDomain The fault domain where the instance resides. You also can use the Monitoring service to create custom queries.Įach metric includes the following dimensions availabilityDomain The availability domain where the instance resides. Therefore, for every minute granularity, the aggregate count is always six, the aggregate sum is the sum of the six data points, and the aggregate average is the average of the six data points. A batch of six of data points is emitted every minute. For example, DiskBytesRead is aggregated across all the instance's attached storage volumes, and NetworkBytesIn is aggregated across all the instance's attached VNICs.įor metrics emitted by the metric namespace oci_computeagent, data points are sampled every ten seconds. I have searched but didnt find a soloution for my problem. The metrics in this namespace are aggregated across all the related resources on the instance. I appologise in advance if this has been answered on the forums. To get these metrics, enable monitoring on the instance. The metrics listed in the following table are available for any monitoring-enabled compute instance. The compute instance metrics help you measure activity level and throughput of compute instances. For more information, see Enabling Monitoring for Compute Instances. The instance must also have either a service gateway or a public IP address to send metrics to the Monitoring service. Compute instances: To emit metrics, the Compute Instance Monitoring plugin must be enabled on the instance, and plugins must be running.Metrics exist in Monitoring: The resources that you want to monitor must emit metrics to the Monitoring service.For more information on user authorizations for monitoring, see the Authentication and Authorization section for the related service: Monitoring or Notifications. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which compartment you should work in. The policy must give you access to the monitoring services as well as the resources being monitored. IAM policies: To monitor resources, you must be given the required type of access in a policy written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool.But unlike most probes, which are implemented in LANs where bandwidth and connectivity are cheap, the ASE is designed to sit at the expensive edge of WAN traffic and leave as small a footprint as possible. At first I found this odd, as probes usually offer a second management interface. When connected on Ethernet to a span port, an ASE must support bidirectional communications. UpTime comes with numerous probes supporting many means of WAN access, including ATM, E1, Ethernet, frame relay, HDLC, PPP and T1. The probes sit passively inline or on a switch span port. to find a service you can rely on, one that can guarantee uptime and promise. This hierarchy puts site performance and event impact in context, and makes viewing performance data more manageable by improving navigation. As long as you have an internet connection, you can log into a system that. UpTime classifies its probes by domain, network, site and WAN access line.
