unity and storops and metrics

Question

Hi, Apologies for question, but not sure who to ask. I see in https://pypi.org/project/storops/ That supported metrics system read/write/total IOPS read/write/total bandwidth disk read/write/total IOPS read/write/total bandwidth utilization response time queue length lun read/write/total IOPS read/write/total bandwidth utilization response time queue length filesystem read/write IOPS read/write bandwidth storage processor net in/out bandwidth block read/write/total IOPS block read/write/total bandwidth CIFS read/write IOPS CIFS read/write bandwidth NFS read/write IOPS NFS read/write bandwidth utilization block cache read/write hit ratio block cache dirty size fast cache read/write hits fast cache read/write hit rate fc port read/write/total IOPS read/write/total bandwidth iscsi node read/write/total IOPS read/write/total bandwidth metrics are exposed. Looking at the methods visible, I see; {'UnitySystem': {'avg_power': 310, 'current_power': 313, 'existed': true, 'hash': 1480349, 'health': {'UnityHealth': {'hash': 2129561}}, 'id': '0', 'internal_model': 'DPE OB BDW 25DRV 256GB 14C', 'is_auto_failback_enabled': false, 'is_eula_accepted': true, 'is_upgrade_complete': false, 'mac_address': '08:00:1B:FF:B2:AD', 'model': 'Unity 550F', 'name': 'dubnas308-spa-mgmt', 'platform': 'Oberon_DualSP', 'serial_number': 'CKM00184801131'}} ['__class__', '__delattr__', '__dict__', '__doc__', '__eq__', '__format__', '__getattr__', '__getattribute__', '__getstate__', '__hash__', '__init__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_auto_balance_sp', '_cli', '_default_rsc_list_with_perf_stats', '_get_first_not_none_prop', '_get_name', '_get_parser', '_get_properties', '_get_property_from_raw', '_get_raw_resource', '_get_unity_rsc', '_get_value_by_key', '_id', '_is_updated', '_ntp_server', '_parse_raw', '_parsed_resource', '_preloaded_properties', '_self_cache_', '_self_cache_lock_', '_system_time', 'action', 'add_dns_server', 'add_metric_record', 'add_ntp_server', 'build_nested_properties_obj', 'clear_dns_server', 'clear_ntp_server', 'clz_name', 'create_cg', 'create_host', 'create_io_limit_policy', 'create_iscsi_portal', 'create_nas_server', 'create_pool', 'create_tenant', 'delete', 'disable_perf_stats', 'disable_persist_perf_stats', 'dns_server', 'doc', 'enable_perf_stats', 'enable_persist_perf_stats', 'existed', 'get', 'get_battery', 'get_capability_profile', 'get_cg', 'get_cifs_server', 'get_cifs_share', 'get_dae', 'get_dict_repr', 'get_disk', 'get_disk_group', 'get_dns_server', 'get_doc', 'get_dpe', 'get_ethernet_port', 'get_fan', 'get_fc_port', 'get_feature', 'get_file_interface', 'get_file_port', 'get_filesystem', 'get_host', 'get_id', 'get_index', 'get_initiator', 'get_io_limit_policy', 'get_io_module', 'get_ip_port', 'get_iscsi_node', 'get_iscsi_portal', 'get_lcc', 'get_license', 'get_link_aggregation', 'get_lun', 'get_memory_module', 'get_metric_query_result', 'get_metric_timestamp', 'get_metric_value', 'get_mgmt_interface', 'get_nas_server', 'get_nested_properties', 'get_nfs_server', 'get_nfs_share', 'get_pool', 'get_power_supply', 'get_preloaded_prop_keys', 'get_property_label', 'get_resource_class', 'get_sas_port', 'get_snap', 'get_sp', 'get_ssc', 'get_ssd', 'get_system_capacity', 'get_tenant', 'get_tenant_use_vlan', 'info', 'is_perf_stats_enabled', 'is_perf_stats_persisted', 'json', 'metric_names', 'modify', 'ntp_server', 'parse', 'parse_all', 'parsed_resource', 'property_names', 'remove_dns_server', 'remove_ntp_server', 'resource_class', 'set_cli', 'set_preloaded_properties', 'set_system_time', 'shadow_copy', 'singleton_id', 'system_time', 'system_version', 'update', 'update_name_if_exists', 'upload_license', 'verify'] Where do I get for example storage processor utilization as a call to 'get_sp’ give me the static data; {'UnityStorageProcessorList': [{'UnityStorageProcessor': {'bios_firmware_revision': '53.51', 'emc_part_number': '110-297-014C-04', 'emc_serial_number': 'CE8HH184100349', 'existed': true, 'hash': 1814369, 'health': {'UnityHealth': {'hash': 2129621}}, 'id': 'spa', 'is_rescue_mode': false, 'manufacturer': '', 'memory_size': 131072, 'model': 'ASSY OB SP BDW 14C 2.0G 128G STM', 'name': 'SP A', 'needs_replacement': false, 'parent_dpe': {'UnityDpe': {'hash': 2129513, 'id': 'dpe'}}, 'post_firmware_revision': '31.10', 'sas_expander_version': '2.26.1', 'slot_number': 0, 'vendor_part_number': '', 'vendor_serial_number': ''}}, {'UnityStorageProcessor': {'bios_firmware_revision': '53.51', 'emc_part_number': '110-297-014C-04', 'emc_serial_number': 'CE8HH184100370', 'existed': true, 'hash': 1480429, 'health': {'UnityHealth': {'hash': 2283289}}, 'id': 'spb', 'is_rescue_mode': false, 'manufacturer': '', 'memory_size': 0, 'model': 'ASSY OB SP BDW 14C 2.0G 128G STM', 'name': 'SP B', 'needs_replacement': false, 'parent_dpe': {'UnityDpe': {'hash': 2283305, 'id': 'dpe'}}, 'post_firmware_revision': '31.10', 'sas_expander_version': '2.26.1', 'slot_number': 1, 'vendor_part_number': '', 'vendor_serial_number': ''}}]} but I assume its some variation of 'get_metric_query_result' to get performance metrics, but I an unsure of syntax of call Any help appreciated;

for reference

Inorder to query metrics, you need to enable it by invoking enable_perf_stats():

```python

import storops

# New unity system

unity = storops.UnitySystem('192.168.100.10', 'admin', 'password')

# Enable matric query

unity.enable_perf_stats()

```

Then, you can get the object and metrics:

disk = unity.get_disk(name=xxx)

disk.read_iops
disk.total_byte_rate

You can refer snmp-agent project for further usage:

https://github.com/emc-openstack/snmp-agent/blob/master/snmpagent_unity/unity_impl/DiskReadThroughput.py

well storops is open source so you can read the source, fix yourself and contribute or create a ticket on github

cadencep45 · Answer

Yup.

But as storops was developed internally, and has a nice python interface, seemed to be worth asking, as its really a question about abstraction.

If metrics are missing, I would simply revert to the REST API as you indicated.

cadencep45 · Answer

True, thanks.

Rainer_EMC · Answer

interesting

I assume that storops just pulls the matrics that are available from our REST API

see the support site for our REST API reference

Its actually also online on every Unity or UnityVSA

you just need to open https:// /apidocs/index.html

Unity
