Question: What methods are available to monitor ECS?
The WebUI (ECS Portal), integrated Grafana, CLI, SNMP, REST API, and Dell SRM are available to provide information about the health of ECS. Also available is Dell Secure Connect Gateway which provides a secure two-way communication between Dell storage systems and the support system for proactively identifying and responding to possible issues. SNMP queries for basic health metrics such as CPU and memory are available as are traps for critical events. Remote syslog support is available. SNMPv2 and SNMPv3 (USM mode) are supported.
Note: ECS 3.8.1 now supports Dell Secure Connect Gateway as EMC Secure Remote Services (ESRS) has reached end of service life.
Question: What metrics does the management system report (such as raw storage capacity, usable capacity, CPU utilization, and current IOPS) and how are they defined?
There is a monitoring page in the ECS UI. It includes metering data for namespaces, or buckets within namespaces, capacity utilization, system Health, transactions, recovery status, disk bandwidth and geo replication. There is also an advanced monitoring section which uses Grafana which is integrated within the ECS UI, it includes data access performance metrics. For more details about these metrics, see the ECS monitoring guide.
Question: What types of Event Notification does ECS provide?
During the ECS installation process, your customer support representative can configure and start an snmpd server to support specific monitoring of ECS node-level metrics. A Network Management Station client can query these kernel level snmpd servers to gather information about memory and CPU usage from the ECS nodes, as defined by standard Management Information Bases (MIBs). It can query the snmpd servers that can run on each ECS node from Network Management Station clients for the following.
SNMP MIBs:
It can query ECS nodes for the following basic information by using an SNMP Management Station or equivalent software:
Question: What are the refresh times for data showed in the ECS UI?
On monitoring displays, you can force a table to refresh with the latest data by clicking the Refresh icon.
Question: What are the definitions for total, used, available, and reserved capacity?
