406  IBM TS4500 R6 Tape Library Guide GLYPH<SM590000> location : A string representing the hardware component where the event originated. This  can be null if no hardware was associated with this event. The location is the same as  specified earlier. GLYPH<SM590000> time : The time the event occurred. Time format is in ISO 8601 format of  “YYYY-MM-DDThh:mm:ss+-hhmm” . For example,  “2018-09-17T23:02:00-0700” . – information – inactiveWarning – inactiveError – warning –e r o r GLYPH<SM590000> severity : string representing the severity of the event which indicates the urgency that  should be given to it. Values include: GLYPH<SM590000> ID : A decimal integer that is the unique identifier of the event in the library. – position_F<f>C<c>R<r> (for example, “position_F1C5R7”) – frameSide_F<f>S<”A”|”B”> (for example, “frameSide_F1Sa”) – ethernetPort_F<f>P<p> (for example, “ethernetPort_F2Pa”). – ioStation_F<f>IO<”u”|”l”> (for example, “ioStation_F1IOu”) – slot_ F<f>C<c>R<r>T<t> (for example, “slot_F1C3R23T0”) – drive_F<f>C<c>R<r> (for  example, “drive_F1C3R23”) – fiducial_F<f>IO<”u”|”l”>L<”t”|”b”> (for example, “fiducial_F1IOuLb”) – fiducial_F<f>C<c>L<”t”|”b”> (for example, “fiducial_F1C3IOuLt”) – frame_F<f> (for example, “frame_F1”) – column_F<f>C<c> (for example, “column_F1C3”) – gripper_A<“a”|“b”>G<”1”|”2”> (for example, “gripper_AbG1”) – accessor_A<“a”|“b”> (for example, “accessor_Ab”) GLYPH<SM590000> location (Optional) : A string representing the hardware component where the event  originated. Hardware components include: GLYPH<SM590000> before (Optional) : A string representing the time before which events should be viewed.  Any event with a time after this will not be returned. Time format is in ISO 8601 format of  “YYYY-MM-DDThh:mm:ss+-hhmm”  or  “YYYY-MM-DDThh:mm:ss” . For example,  “2018-09-17T23:02:00” . If the time zone is omitted the current systems current time zone  is used. When the  GET /v1/events<after>  command runs successfully, the system returns output to  your display, as shown in Example 6-11. The following command attributes are available: Example 6-11 GET /v1/events?after=2019-11-12T06:22:15-0700 command /usr/bin/sg_write_buffer --id=0x10 --mode=2 --raw /dev/sg70<<<'GET  /v1/events/after=2019-11-12T06:22:15-0700' /usr/bin/sg_read_buffer --id=0x11 --mode=2 --length=0x100000 --raw /dev/sg70 [{"ID": "8275", "severity": "information", "time": "2019-11-12T06:24:54+0000", "type": "audit", "location": null, "user": "admin", "description": "A user logged  in to the GUI from 9.145.164.92", "state": null, "errorCode": "0800"}, {"ID":  "8274", "severity": "information", "time": "2019-11-12T06:22:29+0000", "type":  "drive", "location": "position_F1C4R1", "user": "System", "description": "The  state of drive F1, C4, R1 changed from online to unreachable.", "state": null,  "errorCode": "0701"}]
