Hello! As soon as we started using a zabbix mgr plugin, we were faced with the problem of adding a symbol "L" at the end of the values of the unsigned integer types. Looks like that: mgr[zabbix] {'rd_bytes': 3838822714368L, 'total_bytes': 72014131888128L, 'overall_status_int': 0, 'osd_latency_apply_min': 0L, 'osd_latency_apply_max': 1L, … You can see the "L" at and of some values. Google tell me, the this is a normal for Python 2 (https://www.python.org/dev/peps/pep-0237/), but zabbix server can't accept these "wrong" values L. After all zabbix plugin seems to not work. How I can fix that? Ceph-12.2.7 Zabbix server - 3.4.9 Zabbix sender: zabbix-sender-3.4.13-1.el7 Python: python-2.7.5-69.el7_5 — Mike, runs!
