Look at the sql query, there is a limit of 100 built-in: fortiview_request_data()-896: dataset:fv.dest.group tabid:0 _dump_sql()-829: dataset=fv.dest.group, sql:select dstip, max(dstintf) dst_intf,max(dstdevtype) dst_devtype,max(dstmac) dst_mac,group_concat(distinct appid) appid,group_concat(distinct appservice||case when subapp is null then '' else '_'||subapp end) appname,sum(sessioncount) session_count, sum(case when passthrough<>'block' then sessioncount else 0 end) session_allow, sum(case when passthrough='block' then sessioncount else 0 end) session_block, sum(rcvdbyte) r, sum(sentbyte) s, sum(rcvdbyte + sentbyte) bandwidth ,sum(crscore) score, sum(case when passthrough<>'block' then crscore else 0 end) score_allow, sum(case when passthrough='block' then crscore else 0 end) score_block  from grp_traffic_all_dst  where timestamp between 1551397800 and 1551484200 and 1=1 AND ( ft_ipmask(dstip, 0, '91.189.0.0/16') )  AND srcintfrole  in ('lan','dmz','undefined')  group by dstip   order by bandwidth desc   limit 100;
